The claim is that 100 octane was the standard fuel for FC in July 1940, not the RAF.

You can date the transition by the Operating Notes, they are the primary source for technical changes to the aircraft.

It is that simple and elegant, guys. No need to construct elaborate arguments based on circumstance and assumption.
