I have done only one experiment at the time, now I'm improved with doing tests with the computer as Greg Strong was kind enough to include ENEP in his program CHESSV. Fine tunning is impossible but I'm trying different setups mostly for fun! I too have though at multiple ways of tunning among which the ones you mention. And in the ENEP comments section you can see some results of my experiments.
