On occasion I run evo sims with large (1000 BP) bots. Default mutation settings are much too high then to run a sim. I then typically operate at the very minimum possible: 1/32 and max numbers entered, in order to allow for selection and evolution and not degeneration. Even for small bots I have never found myself operating on te right side of the slide. Basically the slide system would operate well if the default mutation probabilities were two orders of magnitude lower (1/100)
