A RAF memo from 1939 confirms all the above:

I've always wondered who had really drawn that graph.

Do you wonder who wrote the memo stating a 28/38 mph increase in speed under 10,000ft?

It will be noted from the service reports that an approximate increase in speed due to the use of emergency 12lb boost of 28/34mph is obtained depending upon the altitude flown up to 10,000ft.

Do you wonder who wrote this graph:




and do you wonder why these numbers are all so consistent? Are you trying to imply that 12lb boost will not result in an increase in speed over 6.25lb boost?

It also seems that you are trying to imply that the RAE Spitfire I data for 12 and 16 lbs boost was falsified? I really hope that this is not the case.
