tests: play shorter games when comparing

The upstream games ran 10000 tasks and the .pqw comparisons 3000 or
2000 more. Differences so far showed within the first few tasks, so
3000, 1000 and 500 keep the tests sharp at a fraction of the time.
Two .pqw save points that tested nothing new are dropped.
