So? For ages you have been swearing black and blue that because the Pilot's Notes stipulated certain engine limitations and certain types of fuels those were the limits observed no matter what, in spite of it being explained to you several times, very carefully, that supplementary slips were issued to the pilots with the Pilot's Notes revising such information when it was relevant.
Now, on the basis of this one test certificate you are saying what? That the engine limitations were
not observed? I haven't noticed any pilot's notes stipulating 10.55 lbs boost maximum using 87 octane fuel, so I guess you want to withdraw all of your previous comments regarding the legal limits etc set by the pilot's notes?
You now want to claim that when pilots refer to pulling the plug it meant they went to 10.55 lbs boost on 87 octane fuel, right? Then present some documentary evidence showing that pilots were authorised to use 10.55 lbs boost on 87 Octane.
Then explain why Dowding found it necessary on 1 August 1940 to send a memo to
All Groups, ALL Fighter Stations and ALL fighter squadrons stating that
+12 lbs boost was only to be used in emergencies? Why not state +10.55 lbs boost, and send a separate memo to the supposedly small number of squadrons authorised to use 100 octane fuel?

Note he also uses the expression "Pulling the Plug" referring specifically to +12 lbs boost.
