I can attest to tuning for problem suites.

On my own program, I was able to tune it to solve 208 out of 300
on Win at Chess in 5 seconds each on a 25mhz 486 (on the same
machine, Crafty solved about 210).

Other programs which could easily beat my program could not do better
on the problem suite.

This is because for the purposes of a problem suite, speed, not
knowledge,
is the most important factor for standard combination tactical suites.
Therefore, a program that is much faster will do well whereas a somewhat
slower but smarter program will do disproportionately worse on the suite
but be able to beat the faster but stupider program.
