Adjusted time
Adjusted time (TA) depends on the timing system
For standard byoyomi:
Adjusted time = basic time + time equivalent to 45 moves in standard byoyomi.
For Canadian Byoyomi:
Adjusted time = basic time + time equivalent to 60 moves in Canadian byoyomi.
For Fischer timing:
As of October 2010 the Rating Commission has approved the inclusion of tournaments played with the Fischer timing system. These are the rules for classify such tournaments: Adjusted time = Basic time + bonus calculated for 120 moves
Examples:
Class A: minimum Basic time 45 minutes, minimum Adjusted time 75 minutes (e.g.: 45 minutes + 15'' per move)
Class B: minimum Basic time 30 minutes, minimum Adjusted time 50 minutes (e.g.: 30 minutes + 10'' per move)
Class C: minimum Basic time 20 minutes, minimum Adjusted time 30 minutes (e.g.: 20 minutes + 5'' per move)
The time per move (in seconds) can be calculated as (Adjusted time in minutes - Basic time in minutes ) /2 This needs to be rounded up
For sudden death:
Sudden death - implying no overtime: Adjusted time = Basic time - is acceptable, provided all other criteria are met.
