Acceleration comparisons

You are making the mistake of assuming acceleration to be constant, but it changes with speed, and changes differently with each plane.
Use the ROC vs speed diagram in Il2compare and I bet it will fit the data okay.
Very rough comparison: La5FN flies 420kph at half time(18s), so lets compare acceleration at 420 to La-5F, ~15m/s to ~10m/s, so 50% better is okay.
