Still too hard to understand?
Heh. You are as genial as ever.
If these charts are accurate, the Hurri I gained just a bit of speed, but the speed curve remains roughly the same as before (hence my interest in who did the testing). One might therefore surmise that the Hurri I would perform marginally better than it did before, not worse, which you suggested.
Whether the plane goes 260 or 275 mph doesn't much matter, because speed was never the Hurri I's strength and virtually all other planes go faster. I haven't noticed any change in the way it handles. Flew it again tonight to test the thought.
Now the Hurri II variants, sadly they are pigs.
