It is a fact the RAF did not complete conversion to 100 Octane until around January 1941. That is evident in the Operating Notes.

Actually you mean January 1942, at a time where there was not a single operational squadron operating the Spitfire I.
The Pilot's Notes page from May 1940 simply doesn't specify which unit should use what fuel, so this doesn't tell us anything about how widespread the use was at that time.

Some people seem to enjoy going in circles, but from a logical point of view it is impossible to prove that "all operational units used 100 octane fuel during BoB".
An analogy - if someone claimed that there are orange ravens, it cannot be disproved by showing thousands of black ones. However, to support the claim, it would be necessary to show a couple of orange ones - that would close the case and therefore, it is the way an argumentation needs to follow here.
Back to the 100 octane fuel, this topic has provided plenty of information and documentation regarding the use in 1940. Papers, memos, storage lists, logbooks, manuals, pilot and ground crew instruction, pilot accounts - all there to prove beyond doubt that 100 octane fuel was used.
What I'm missing is prove of 87 octane fuel being used in operational units. So, can anyone come up with a definite proof that an operational squadron used 87 octane fuel lets say until the end of September 1940?
I think that that kind of info, for instance a squadron logbook dating the conversion to 100 octane fuel in October 1940, would be far more valuable than another 500 posts trying to convince each other of something people simply do not want to believe.

Couldn't agree more and a normal person would understand that, but we have a 'special' person arguing the case against here who is better than all of us. I know this because he flies an aeroplane himself and polishes a 190 for a rich man.

According to his logic there can't have been more than a few thousand dinosaurs inhabiting the earth in total during that great span of a few hundred million years between the Jurassic and Cretaceous periods of our planet, on the basis that these are the only fossils that have been found. Furthermore, if you take into account modern livestock farming methods and regulations then their existence was even more implausible because every farmer knows that keeping a herd of Brontosauruses is not defined anywhere and they wouldn't fit in a modern cowshed for milking.
