This is only a false interpretation propagated by Crumpp. The 2,850 rpm/3,000 rpm restriction is the 30 minute climb rating (+6.25 boost). In normal conditions this is restricted to 2,600 rpm, in combat/emergency condition however 2,850 rpm is permitted below FTH and 3,000 rpm above FTH.

Just think about it: It is not possible to achieve +12 boost above FTH, why put a restrict on a boost for an altitude where this boost is not possible?

But enough of Spitfire talk, this topic is about Bf 109.
