Dynamic Overall
To be honest I think its pretty good so far. Can be quite sensitive, too much particularly for Goalkeepers and defenders if rested for only 1 game they tend to drop from green to red. I'm okay with that as momentum is a major factor of form in real life.
My problem with dynamic overall is with the INTL teams. I'm France manager, winning my qualifiers in dominant fashion but my high performing players are getting the opposite treatment to club football. Basically, playing well or playing at all gets punished with bad form making it really difficult to be in good position come the later stages of the Euros/World cup. Just seems to be completely backwards.
Also the commentators keep recommending I buy foreign(non French) players to add to my French national team.
