That is how it works.

The 87 Octane limiting operating conditions are published as the predominate operating limits of the aircraft in June 1940. References to 100 Octane are minor footnotes denoting specialized circumstances that are not the common configuration.

So how do you know it worked that way? Source please.

Here is evidence that it didn't work that way:

Hurricane I "operational limitations" May 1941 (thanks Klem):

Spitfire I "operational limitations" January 1942 (I'm sure someone has a better copy of this)

Merlin II, II and V "operational limitations" November 1940

In all of these publications 100 octane fuel and +12 is only a "minor footnote" and the "All out" limit is given as +6 1/4.

And the explanation for this is given in Pilot's Notes General (1st Edition 1941, not the 2nd Edition).

We know that the Merlin II and III was designed for 87 octane and therefore the operational limits are always given for 87 octane.
