I think >it's quite a problem to define. I think you first have to use the same time limit. And even then, it's not clear what solving such positions has to do with the game of chess. IE I have seen several material-only test engines that do well on the suite since the goal is to win material or mate the opponent. Don Beal's first null-move program did quite well with no evaluation at all other than counting pieces, for example. Most of us have been running WAC for several years, and everyone has been using 1 minute as the normal time limit. That's pretty long by today's standards, but it maintains compatibility with results from 2-3 years ago. I can produce results for any time limit you'd like, however, to start a new time limit...
