Spitfire supposed to dive better than the 109?

One thing that struck me about that posting is how measured the results were, the pressure that had to be applied, the point at which the weasurments were taken, the time taken to bank at a set speed and so on. Clearly they were not just relying on the pilots opinions.
Excellent posting and that Gloster looks as if it would have been well able to take care of itself, what a roll rate.
