PE_Tihi,
Your reasoning makes sense to me. Where I disagree is about power (and power loading). In my opinion, max power time limitations have mainly to do with long term engine life. In combat situations, pilots used all they had, as long as the combat lasted (which usually was a very short time).
I agree with you that 21 m/s are way too much climb for the poor old I16. However, I have some doubt about the 109F having an “immensely” superior climb rate. According to my sources, its power loading was 2.11 kg/hp, not much better than the Emil’s 2.21 (or 2.27, according to my sources), and almost equal to a Type 28 at max continuous power (2.15, according to you). By comparison, an I16 type 24 (four gun model), weighing 1880 kg, had a power loading of 2,02 at maximum continuous power (930 hp), and an impressive 1,7 at max power for two minutes.
All of these numbers, anyway, should be regarded with some suspicion. Average operational planes, flown by average pilots, rarely reached peak performance.
