Inaccurate performance data for BOB fighters in COD comparing to RL data

[Glider]

I know this is going to sound very obvious but I have always believed that pilots notes were there to help the pilot avoid crashing the aircraft, not an historical document showing the roll out of things like fuel.

Now I know why most of my flying experience was in Gliders, none of the smelly stuff that can catch fire.

It is a fact the RAF did not complete conversion to 100 Octane until around January 1942. That is evident in the Operating Notes.

This is total bull, I would love to see you prove it, why not March 1942, or even have a punt at 1943. Why not 1944 as I know there was a shortage of 100 Octane just before the Invasion, maybe they converted some squadrons back to 87 Octane, they didn't, but what the heck, there is more logic for such a move as there was a shortage then.

Its worth remembering that you still haven't shown us the pilots notes for the Spit I you were quoting as being June 1940. So why on earth should we believe that it was as late as 1942
