'Perfect' seems like overstating the case.
I was going to write the same thing, though my suggestion would be "Rational reasoning / decisionmaking". Well, maybe repeating the same word everywhere is not a good idea. Therefore, another suggestion: "Better reasoning / decisionmaking".
"Perfect" leaves me twitching. Is it possible to know with probability of 1 that your reasoning can't be improved on if you're talking about anything complex?
