This is a Spitfire V with metal covered ailerons, tested up to 300 mph. The Spitfire I/II with fabric covered ailerons are a lot worse, and at 400 mph IAS pretty much hopeless - ineffective ailerons combined with a rather flexible wing. British tests indicate a roll rate of about 12°/s at 400 mph with 50 lbs stick force for early Spitfires - in other words half a minute for a 360° roll.
Also sorry for the cheap joke above, but I would say that while people may not disagree on the math, they may very well have different opinions regarding the input and different interpretations regarding the output. I'd also say that anecdotal evidence is valuable in getting input and interpretation right. For example, popular numbers regarding sea level top speed show the F4F to be faster than the A6M-2, however, anecdotal evidence from both sides agrees that the A6M-2 could and would outrun an F4F. A good enough indication that the numbers are not plausible and some research is warranted...but data for the A6M-2 just isn't around in quality and quantity as it is for say Spitfires and 109's.
