There is a grey zone, or maybe schroeders cat, which isn't, and can't be, defined.

The compromise solution might be that the overwhelming majority did use 100 oct.

There is a black and white dicotomy:

White: There is evidence for numerous combat sorties by BofB Hurricanes and Spitfires using 100 octane fuel.

Black: There is NO evidence for even a single combat sortie by a BofB Hurricane or Spitfire using 87 octane fuel.

There is NO grey zone, because if there was, there would be evidence for combat sorties with 87 octane fuel along with 100 octane fuel.

Theory: 100 octane was used exclusively by front-line RAF FC Hurricanes and Spitfires during the BofB.

Theory predicts that combat reports would be uncovered showing 100 octane use. These reports exist and have been brought to light; the theory correctly predicts the evidence.

Theory: 87 and 100 octane was used by front-line RAF FC Hurricanes and Spitfires during the BofB.

Theory predicts that combat reports would be uncovered showing 87 octane use. These reports do not exist, and none have ever been published.
The theory fails the evidence test.
