I fear that you have not yet quite understood my position.

Pips noted that in May 1940 the British decided to stop the roll out of 100 octane and limit it to apprx. 25% of the force.

We of course know from the papers in AVIA 282 that in May 1940 the British indeed noted that they have supplied 100 octane to select fighter stations and a number of bomber stations.

Pips also noted that later when the supply situation eased they decided to continue with the changeover. Pips noted that the changeover was completed by the late autumn.

We also know from the same AVIA papers that it was not until early August 1940 the British finally decided to authorize 100 octane use for all operational aircraft. Of course it was just that, an authorization. The actual steps took some time.

From the fuel consumption and issue papers we know that 87 octane was the primary fuel, and 100 octane issues only increased towards late September 1940.
