Spitfire supposed to dive better than the 109?

The problem with the evaluation in this report is imo, that it seems that the british fighters had to come out as the better ones and so the ability to turn was the priority.
The other tactics, which might have favored the 109, weren't evaluated.
Other than that this test even proves that it took experienced pilots to outturn a 109 in a Spitfire because of the sensible high speed stall characteristics.
