An incredible 297/300 on WAC at 5 seconds (actually 4.9 seconds) on my machine
(and one of those is solved in 5.43 seconds). The problems missed:
WAC.100 {takes 18.5 seconds}
WAC.141 {takes 5.4 seconds}
WAC.230 (...well, nobody's really sure if it even has a solution...).
The best I have ever seen. I think probably Yace will win my contest.
