**New Tournament Rating Calculating method**

to determine ratings of **players with 1 rating above 1800**, where

there is a "small" sample size and

Where the players next highest rating has a greater than 100 game history.

The next highest rating - will "weigh" that rating with a 100 game weight.

That Rating will be combined in proportion with the >1800 small sample rating as

described below:

Example:

Use this formula, to find a Tournament Rating:

(>1800 rating x small sample game total) + (Lower rating x 100 game weight) = (Multiplied ratings / combined game total) = New rating.

Example of the One time this rule has been used "so far" in this tournament:

Exselsior's new RC tournament rating will be

(Glb) 1714 x 100 games + (4v4) 1874 x 26 games = 220384/126 = 1749 Combined adjusted rating

Any Players with 2 ratings above 1800 will Not be able to participate in the <1,800 rating tournament.

Remember >1,800 players....

There is going to be another open Rainbow Cup at end of February where

historically everyone above 1,800 has

been picked to play in the 12 team, 3 man teams.

Hope to see you soon in the next Open!
