After following this thread with growing disinterest i believe the conclusion, without any personal opinions, should be:

As there is lots of evidence for the use of 100 octane fuel by operational fighter units before and during the BoB this can be taken as a fact.

However that isn't the proof that all operational units did actually use 100 octane fuel only.

The use of 87 octane fuel wasn't documented, as it wasn't special, only diversions from the norm are remarkable.

That means that the use of 87 octane fuel by operational fighter units can't be generally ruled out for lack of proof, even if the evidences indicate otherwise.

Imo, of course.
