Don't spout your BS on me hightone. I said none of those things, and if you bothered to read 1 post of mine in this thread before trolling a reply you'd notice I was taking the exact opposite stance.
As for time to climb, the A6M2 was reported making the same alt in 6 minutes and change.
Edit: Wait, I'd have to check again, might have been 16-17k range.. still, what I was looking up had the model 21 outclimbing the model32.
EDIT: Wmaker, I too read the comment "dissappointing comapred to predicted numbers" but also have read, specifically, pilots did not like that it climbed and turned marginally less than the plane it was replacing. You're thinking of a different reference than I am.
