It is known that some engines can benefit more from longer time than the others, resulting in rating differences. Otherwise we would all test in blitz and be happy with that. Agreed. Although I have no evidence to support this, I'd guess that the speed increase for an engine would benefit it most at a shorter time control. Then, when the time control lengthens an engine surely reach a sweet-spot where in the time available it will give it's best answer 90 % of the time. Then, going even longer, it surely reaches a point where no matter how long you give it, it will always give the same move, because the limitation is then it's knowledge and evaluation rather than the speed or time available. We have only been going for 2 months or so, and naturally we don't have as many games yet as we'd like because we started from nothing. But in another 3 months most of our major engines will have over 1,000 games each and the error margins acceptaby small. Once we reach that point, new engines including amateurs will be able to be tested quickly even with the longer time control.
