Ha, ha! >The exel table is fantastic. So much work which makes so little sense! >Incredible! The value 2600 at the beginning of that formula has NO INFLUENCE on the rankings. It's just added for convenience obviously, to create ratings at a common level, for easier comparison. IMO the important part is 2*number_of_solved_pos_in_% - 5*solution_time_in_min/100 This just means that a maximum of 200 points can be reached by the solvings, but the time required to solve can reduce that value by up to -100 points (5*20 min./pos.*100 pos./100). IOW., the percentage of solutions has 2/3 influence on the rating, and 1/3 is determined by the time consumption. This makes sense for a difficult test (only few engines solve 70 pos. or more). The solvings are the main thing, and in addition to that the times can provide a finer grid (i.e. to rank engines which have the same number of solutions). I don't understand your sarcasm about this... do you have a better rating method for tests? Btw. no, I say RATING (test rating), not Elo. Forget about Elo. Tell me your great universal formula which is beyond any critizism. :)) Steve
