First, sorry, but I don't have any hard numbers for you. But for many iterations of this game more/less offense/pitching was the only league evolution option I would enable and in my experience there were noticeable changes or fluctuations over many years, much more than what I would see without them enabled.
As to the LTM's and PCM's etc it does not change those in any way.
With all that said I did not use it last version and have not had enough time with this version yet, so hopefully someone else can be of better assistance
