@Eonwind, I guess in theory you could use the black box approach which we were given to reproduce and compare the current and an year old PS to either support or prove our claims wrong. That, including OS, hardware, database engine, datasets, PS version and whatnot that has anything to do with random and floating point numbers. But that is an impossible mission if you ask me. I’d rather go with rebalancing the system for a desired target.
@Boni, You're right the change are not so new... I dont really remember but it was almost suddently... like ON/OFF.
