I'll see what figures I can find for that, if any.

Agreed. Unfortunately the Spit IX manual only mentions the MP/RPM settings for most economical cruise speed...no doubt operational settings were discovered by the same method, however, setting +7 boost and reducing RPMs to achieve the desired cruising speed.

I am far of being a good pilot, just curious.

How does the lack of pilot fatigue to high Gs affects tactics?.

Is it more important than this new adjust to the FM?.

Pulling 2+ Gs and indeed high stick-loads for extended periods is absolutely exhausting, by all accounts. That would affect a pilot's vision, resistance to blackouts and their ability to pull the lbs needed to make such high-G turns in the first place.
