Have you seen the chart(s) that 1C has used? IC has adjusted the RAF fighter FM's downwards accordingly and I'm frankly puzzled by this turn of events and the reasoning or logic behind it.

Hi. No, I didn't see the 1C measurement results, but i don't understand, B6 why would say this, if it's not true.
ps. Some kind of Clod-compare would be the best. Everyone would be happy if we can get accurate and detailed performance graphs.
