"Consistently" is not a mathematical word :) So it depends how you read "winning consistently", it could mean just winning on average, or it could mean it wins all the time ie. never losing or even drawing. I think the latter is too strong, ie. if you have the match results 60-40, 55-45, 89-11, 48-52, 61-39.... I'd still say one engine here is winning consistently, ie. it is who wins on average that is the most obvious interpretation. Reading it like that the statement becomes logically equivalent to saying it is a shared number 2 engine in the world. Since nobody other than Shredder can beat it on average all the other engines must be either weaker or of equal strength, at least given the specified test conditions. -S.
