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

[Crumpp]

All very well and good - how about finding some documentation confirming your speculation about the RAF using 100 Octane for nothing more than operational trials?

The fact the RAF did not complete conversion to 100 Octane until around January 1940 is evident in the Operating Notes.

The documentation is posted and been posted several times.
