TTT Rating System

Introduction

TTT Rating System (a replica of TTCAN Rating System) keeps track of AB players' ratings changes when the players play in recent and going forward, future TTT tournaments.

This is needed because AB tournaments are not to be sanctioned by TTCAN in the foreseeable future, and therefore, TTT tournament results will not be forwarded to TTCAN for ratings calculation purposes.

As a service to TTT tournament participants, TTT Rating System will process the results instead, and perform the same ratings calculations.

Viewing a player's rating

When not in a tournament environment
Menu - Player Info :
Explore using different "Search in" options to find players in specific or all provinces.
This will give the current rating of searched players.
[The current rating may be different than those in previous tournaments]
[Gives you a list of players satisfying the search criteria]
When in a tournament environment. That is, when you had done Menu Tournament Select and select a tournament first. Now, all the ratings mentioned would be from the set of ratings used for that tournament.
Menu - Player Info :
Same as above.
Menu - Reports - Player Results :
Displays a player's details first, and then all the results (with rating points exchanged) for each rated match in the tournament.
Menu - Reports - Player Registration :
Displays a player's registration details (must know the password used to access it).

What is "Period"?

Just a number to indicate when the rating was calculated.

TTCAN uses a simple number that is incremented when a calculation is done, usually every month.

TTT uses a different number formatted as YYMM when a calculation is done, again usually every month in step with TTCAN.

A special period of 0 means that the player is a new player participating in the TTT tournaments.

In general, Period and Cycle mean the same thing.

How to read Player Results?

Step 1.

Confirm the player's name so as to get details of the player.

The Rating field has the rating for the player at the start of the tournament.

Step 2.

Click Show Results so as to get the points exchanges for all rated matches for the player in the tournament.

Each match will have a winner and a loser, and the winner gets WinnerPX points, and the loser gets LoserPX points (which is zero or negative). The player's points exchanged are highlighted in "red".

Step 3.

The Adjustment line shows the player's won/loss points exchanged.

Expected rating is calculated using the following formulae.

ExpectedRating = StartingRating + AdjustmentWinnerPX + AdjustmentLoserPX.

The result of the calculation will be the player's rating for next cycle's tournament(s). Provided that the player doesn't play in any other tournaments during this cycle.

If the player do play, during this cycle, in other tournaments, the player's rating for next cycle will probably be the summation of the changes for the tournaments.

Special Handling of TTT updates?

Case 1: non AB players

Players from other provinces participating in TTT tournaments WILL NOT have their TTCAN nor TTT ratings updated.
Basically, all TTT tournaments are Non Rated. There is no collection of rating fees at all.
TTT will not manage non AB players ratings.
TTCAN will continue to manage non AB players, but we will not submit non AB players' matches to TTCAN.

Case 2: AB players playing in TTCAN sanctioned tournaments

Match results from those tournaments will be sent to TTCAN by the tournaments' organizers.
AB players' match results will be processed against the player's TTCAN ratings and their ratings updated appropriately.
But those ratings are typically out of sync with their TTT ratings.
Instead, TTT will take the increase or decrease between a player's TTCAN latest rating and his/her immediate previous rating.

For example, for 2024 May cycle of TTCAN (period 398), two AB players participated in a sanctioned tournament.

Before the tournament on TTCAN, the players' rating were:
2414 for Jason on period 397,
900 for Jesse on period 392.

After the tournament on TTCAN, the players' ratings became:
2432 for Jason on period 398,
991 for Jesse on period 398.

Thus, the increase for the players on the TTCAN side for that tournament:
18 points for Jason, and
91 points for Jesse.

And for the TTT 2405 cycle, the players' ratings were calculated as:
2453 for Jason, and
953 for Jesse.

Taking the increases from TTCAN, the players' TTT ratings are adjusted to:
2471 for Jason, and
1044 for Jesse.

This might seemed to be quite complicated, but if you look at TTT and TTCAN are two different systems handling different tournaments, and whatever is updated on TTCAN, differences will be calculated and transferred to TTT, the complication is quite reasonable.

QED.
