Another essential factor in touch the atmosphere of meritorious norms for every Category of tournament. Players should meet or surpass the related rating to illustrate that that they had carried out at Grandmaster (GM) or International Master (IM) level. Scores have been expressed as percentages of an ideal most rating and lowered because the event Category increased, thereby reflecting the power of a player’s opposition and the relative problem of the task.

Tournament organisers might then apply the chances to their very personal event format and declare prematurely the precise rating that contributors should obtain to realize a GM or IM consequence (nowadays known as a norm).

To qualify for the Grandmaster title, a participant wanted to realize three such GM outcomes inside a rolling interval of three years.
