all the FM improved

Well that is good news if that means he tweaked the FMs to better match/conform to the real world data performance..

And

But bad news if it means he flew a few more one on one df missions with his buds and determined they, in their MiGs, are still shooting him down too often in his F86 and thus he increased the power of the F86 some more..

Which is the problem with any/all FMs that are based on personal preferences instead of real world data.
