No The default version is usually not the strongest because programmers cannot tune every parameter to be the best because they may need thousands of games for that. The pawn value in the default personality may be 100 It is possible to increase the default value to 101 or to reduce it to 99 In most cases one of this options is going to be at least 0.1 elo stronger than the default personality because programmers have not enough time to play more than 1,000,000 of games to detect difference of 0.1 elo. Same for other default values. Uri
