I think it is fairly clear (in a fuzzy way :) ) that @results off a tired or tiring pitcher are NOT automagically "re-rolled" by HAL. We had previous threads about @results _sometimes_ being hits and _sometimes_ being outs which lead to various arguments on that topic.
I'm not sure how I "feel" on this one. I get the feeling that they attempted to create a very realistic gradual yet somewhat random algorithm for pitchers to get worse as the game wears on based on MANY factors (pitch count, POW, previous hitters results, F-Number, etc.) that are probably very hard to explain in 4 or 5 bullet points on a help page. Would I be happier with a much simpler system? I'm not so sure. If Bernie published the, say 50 box flowchart with what "really happens", I'm sure every result that some people didn't want would be endlessly complained about anyway!
A little ambiguity in the game, in some ways, makes it more interesting. I'm interested, and will continue to study the issue and hopefully use it to more expertly set my pitcher's preferences. But, we just got super HAL bullpen logic, so more research is certainly needed.
Based on what I have seen so far F0 and F1 pitchers are REALLY bad.
