Information for Event Directors

This page explains how to become an event director and submit events to the STIGA World Ratings/Ratings Central.

Rating Scale

In order to be a Ratings Central event director and submit events to Ratings Central, you must have an understanding of the rating scale that Ratings Central (and USATT) use. In other words, you must know what it means to be a “1500 player” or a “2000 player”, and you must be able to watch a player playing a match and estimate his level to within a few hundred rating points. To assist you in understanding the rating scale, we have provided some videos. If you need further assistance, please .

Submitting Events

There are four ways to submit events to Ratings Central. You can use Cantor, Zermelo, René Nielsen's Table Tennis League Software, or your own software.

Both Cantor and Zermelo are Windows apps that you run on your own PC. (There is no Web form for submitting events becase Cantor is much easier to use than a Web form.) System requirements are any computer running Windows 98, 98SE, ME, 2000, XP Home, or XP Pro. I would guess they will run on Vista, but I haven't tried them; if they don't, let me know. If you have a Mac, you'll need Virtual PC. For Zermelo, you'll need a printer and your screen resolution must be at least 800 by 600 pixels.

To submit events, you will also need an Internet connection. You do not need to be connected to the Internet while the matches are being played, but you will need to be connected when you are ready to submit results to Ratings Central.

Cantor's sole purpose is to let you record results and submit them to Ratings Central. Cantor can be used with any event you run, regardless of its format.

Zermelo's purpose is to make running table tennis tournaments simple. Zermelo handles all aspects of running a tournament, including submitting the results to Ratings Central. Zermelo also has support for running USATT-sanctioned tournaments. While Zermelo can handle most of the popular tournament formats, it cannot handle all formats. Cantor is easier to learn than Zermelo is because it does less.

René Nielsen's Table Tennis League Software makes running a league simple and fully supports Ratings Central.

If you have been using your own software to run your event, please to find out how you can interface your software to Ratings Central.

For more information on Cantor and Zermelo, please download and run the setup programs. Each setup program installs the application and the user's manual. You can also download the manuals separately, if you want to look at them without installing the applications. You need to have the free Adobe Reader installed to view the manuals.

Registering as an Event Director

Before you can submit any events to Ratings Central, you must register as an event director. To do this, click on the link at the bottom of this page and fill out the form. We will review it, contact you if we have any questions, then let you know when we have activated your account.

Once your account is activated you will be able to use Cantor and Zermelo to submit results. You will also be able to use the Ratings Central website to download a rating list (including player mailing and email addresses), download a club list, update your director information, add or modify club information, update player information, and associate players, directors, events with your clubs. To do any of these things, simply log in at the left using your director ID number and password. When you are ready to run an event, you will want to download a rating list and a club list for importing into Cantor or Zermelo.

Event Minimum Requirements

It is up to you what events you submit, but here are the minimum requirements:

• The event must have some sort of definite structure, for example, round robin, single or double elimination, team match, league match, ladder, winner stays. In other words, it must be more than just getting a bunch of players together and having each play whomever they wish. In particular, two players going to the club and playing each other half a dozen times is not an acceptable event.
• You must submit all matches that are part of the event, not just some of them.
• The event must be open to some segment of the public, for example, anyone who pays the entry fee, club members, students at your school. In other words, more than just your friends.
• The event must be publicized in some way, for example, mailing or emailing entry forms, posting a notice on a club website, handing out flyers, posting a notice in your club.
• You must do your best to collect accurate information (name, sex, country) on each new player and to correct any errors in such information for existing players.

You don't have to use Ratings Central ratings for seeding or eligibility, but of course, you are welcome to.

Here are some match cards you can use at your events:

• Best of 5
• 3-person team, best-of-9 matches

Unrated Players

Before running an event, please read about assigning priors for unrated players. This explains how (and when) you should specify means and standard deviations for unrated players who play in your events. Besides being available by clicking the link, this information is also in the Cantor and Zermelo User's Manuals.

Cost

There is no charge to become a table tennis event director, submit table tennis events, or use Cantor for this purpose. If you are involved in a sport other than table tennis, please so that we can discuss your particular situation.

Zermelo may be used to run almost any table tennis tournament, not just tournaments that you submit to Ratings Central. If you use Zermelo to run a tournament that you are not submitting to Ratings Central, then the cost to use Zermelo is $20 per tournament. There is no charge to use Zermelo to run a tournament that you do submit to Ratings Central. In other words, as long as you submit the tournament to Ratings Central, there is no charge to use Zermelo, regardless of whether you also submit the tournament to some other organization.

For the cost to use René Nielsen's Table Tennis League Software, please see René's website.
