Today is Yom Kippur, a major Jewish holiday. I'm not Jewish, but the local schools celebrate it and are closed today. If the kids I coach get the day off, so do I! So no blog today. But to tide you over, here's a repeating gif image of a cat at the net as two players play. Either that or this one of minions playing table tennis should be on your club's home page. 

USATT Rating Inflation

I blogged about this back on June 19, 2014. The subject came up last night during the USATT Teleconference, where we were discussing creating USATT leagues that would be processed with regular USATT ratings, rather than the separate USATT league ratings that are currently used in many leagues. The question was whether we needed to use adjustments. I explained why the rating system would actually deflate without adjustments, but that in the past we've had the adjustments too high, which led to inflation. I've experienced this in the leagues I've run or been involved with, where over and over we've seen the ratings deflate, leading to us putting in an adjustment factor. (At MDTTC, we give bonus points for winning your group.)

Until now, I've always assumed my analysis of this was my own from about 15 years or so ago, and didn't realize anyone else had studied this. (I have a bachelor's in math, and if not for table tennis might have become a math professor…) Here's how I explained it back then.

"If there were no adjustment factor, the system would be deflationary, and the average rating would be dropping. Why? Because the average player improves after his initial rating. Assuming no adjustment factor, let's say that the average first rating is 1200, and that the average player then improves to 1500. That means the player takes 300 rating points from others in the system. Result? Assuming the same number of players in the system, there are now 300 less points distributed among them, and so the average rating goes down - even though the average level of those players has stayed the same. This should be true of any rating system where there's a direct or indirect exchange of rating points."

MDTTC and USATT Activities

Lots of stuff going on right now. Here's a quick rundown.

We've finalized the teams and schedule for the new season of the Capital Area Team League. I'm on the organizing committee as webmaster, along with Commissioner Stafano Ratti, Treasurer John Olsen, and Publicist Richard Heo. Play begins this Saturday.

On Thursday and Sunday I ran the first meetings of the Fall junior programs I run at MDTTC. We have twelve new juniors, ranging in age from 5 to 13. We focused on grip, stance, ball-bouncing, and the forehand. Next up: the backhand and serving. On Sunday we also had a staff meeting to discuss upcoming plans for the programs.

On Sunday we had the first meeting of the new "Talent Development Program" at MDTTC, where ten of our best kids in the 7-9 age group met and trained, with five coaches – yes, a 2-1 ratio. We may have more depth in that age group than ever before. I don't think of this group has played tournaments – but that'll be happening soon. The program is sponsored by HW Global Foundation. Watch out China!

Also on Sunday was the weekly meeting of the MDTTC Adult Training Group. I also have two regular students on Sundays, but coincidentally both were away or unable to attend, so I had most of the morning and early afternoon off for a change.

I'm buried in USATT work. (I'm not alone on this – I'm working with other USATT people on many of these. CEO Gordon is helpfully involved in most issues.) A short rundown:

If You Want to Compete, You Have to Cheat

This headline isn't technically accurate - there are a few top players who serve legally, and are still able to compete. Vladimir Samsonov is perhaps the best example. But the gist of the statement is correct - at the higher levels, since players are allowed to illegally hide their serves, players who do not cheat are at a substantial disadvantage. (The other major cheating problem in table tennis is boosting, which I discuss and give my solution to in this blog, which I will submit later as a rules proposal.)

I've been torn about whether to post pictures of all the USA cadets hiding their serves to show the extent of the problem. They're only kids. But the videos are public, and so anyone who isn't blind can see them. And I don't really blame the cadets who hide their serve in response to an opponent who does so and gets away with it - they are doing what they need to do to compete, and what they are coached to do, because the rules aren't being enforced or fixed. (I often look to see who does it first in a match– that's the one I do blame. You definitely shouldn't be hiding your serve unless the opponent does so far and gets away with it.)

How bad is the problem? At the 2014 U.S. Open there was only one top cadet regularly hiding his serve. He made it to the final of Under 14 Boys, where he met up with a strict umpire. After getting warned on the second serve of the match (and I think faulted later on), he served legally and lost. 

But since that time, in tournament after tournament, umpires did not enforce the rule, despite regular complaints from opponents. The result? It became obvious that illegal hidden serves were allowed, and that those who used them had a large advantage. And so, one by one, the other top cadets began to illegally hide their serves. 

A Burned Finger, Arm Problems, a Cold, and a Deviated Septum, Oh My!

Let's take these in order. (Oh, and remember junior star Jessica Shen from the 1990s? We'll get to her.) 

On Monday, I over-microwaved spaghetti for lunch. When I took it out a gob of boiling sauce hit the back of my right index finger. The skin blistered - it was pretty bad. I ran cold water over it for a while, cleaned it, put antiseptic on it, and bandaged it. It's been hurting like crazy ever since. Worse, when I'm hitting backhands with my students the back of the index finger faces the student - and about once every 15 minutes someone smacks it with a ball. OW!!! I may have to put some padding on it for tomorrow. 

On Wednesday, while hitting some hard backhands with a student, my arm started hurting a bit. I've blogged about this a few times; I wear an arm brace that really helps. But while the brace mostly protects it, I have to be careful not to make it worse. Note to self: no more very hard backhands for a few days. 

On Tuesday (yes, I'm going out of order), I woke up with a slight cold. I was blowing my nose and could barely breathe except through my mouth. It was pretty tiring. It's only a minor cold, but it would be nice if it decides to go somewhere else. Maybe to this guy. 

Type of Table Tennis Forum Members

Here's a hilarious new video (12:27) that talks about the various types of people you find on a table tennis forum. It's spookily accurate!!!

I used to be very active in online forums, but in recent years not so much. Why? It was a combination of dealing with what the video calls "1500 Experts" and trolls. Often someone would post a coaching question, and I'd answer it, only to be contradicted and even scorned by these "Experts." Let's just say that there are some very opinionated people out there who haven't actually done anything in table tennis, and frankly speaking, don't know what they are talking about. This doesn't mean there aren't lower-rated players who are knowledgeable about table tennis, but they are outnumbered and often outposted by those who are not but believe otherwise.

One that comes to mind was a guy who argued strenuously with me about forehand looping technique. He'd argue to the ends of the earth that you only use your arm for the shot, no legs or hip rotation, and talked about his revolutionary methods that gave him a more powerful loop than those taught by the clueless people who taught table tennis. He admitted he'd never been to a table tennis club or tournament, nor had he played any top players, but he knew. He KNEW.

I've also had to deal with way too many trolls. I made the mistake (please slap me) of trying to have reasonable discussions with a few of them, and let's just say that never worked. I learned.

My Weekend

Here's a short rundown of my weekend, Fri-Tue morning.

Today is Rosh Hashanah, the Jewish New Year. I'm not Jewish, but the local schools celebrate it and are closed today. If the kids I coach get the day off, so do I! So no blog today, and the Tip of the Week will go up tomorrow, as I sleep late. But not too late – I've got a long todo list today involving various USATT, MDTTC, and CATTL issues, plus some private coaching tonight. (You may notice I'm putting this up at about 4:15 AM Monday morning. Guess what I've been doing all night?) But to tide you over, here's an…

...Incredible Doubles Rally at the Belgium Open

Here's the video (38 sec) between the Koreans and Hungarians in the semifinals at the Belgium Open held last weekend. Hungary won the match! (They'd lose the final. See Men's Doubles results.) 

Some Ping-Pong Reading?

Why not spend some of your weekend (or next weekend) reading some table tennis books? Or are you one of the 28% who haven't read a book in the last year? No, table tennis players are too smart, and of course are voracious readers. Here's my table tennis book collection – currently at 234 books and 13 feet of shelf space. You could, of course, just read my books - here they are. (Here's my Amazon page.) Or you could browse these, mostly from the last ten years.

Fixing the Grip

Here's an interesting coaching story. I've been coaching one junior for about three years. Over the last year he's grown about six inches and his hands grew even more –at age 14, they're as big as mine. During his first three years his biggest technical problem was a tendency to stand up too straight, which affected his strokes. In particular, it led to a tendency to stroke too much upward. Often his strokes would start forward and then go upwards as he contacted the ball, which is the natural tendency of players who stand up too straight.

Over the past year, as he's grown, he's run into another problem - he began to forehand loop with mostly his upper body, with less and less legs and hip rotation. I kept harping on this, but he had difficulty doing so. At the same time, he seemed to overcome his problem with standing up too straight, adopting a very wide stance that kept him relatively low. So we'd sort of swapped one problem for another. 

And then, a few weeks ago, he sort of "confessed" something to me - that he'd been changing his grips much more than I'd thought. Yes, grips.  

I'd known that, like Waldner and many others, he had what I thought was a minor grip change from forehand to backhand, where he'd put pressure with the thumb on backhands, which rotated the racket slightly into the backhand position. However, over the last year - probably because his hands were getting bigger - he'd begun using more and more extreme grip changes, to the point where he was now using a relatively extreme backhand grip for backhands, and a relatively extreme forehand grip for forehands. And he was running into all sorts of problems in rallies as he tried (often unsuccessfully) to switch back and forth. The subject had actually come up about six months ago, but at that time it was only a minor forehand and minor backhand grip, and he wasn't having quite as much trouble switching yet.
