That looks like somebodies photo-shop work.

Here is the page from "Operational Notes for Pilots on Merlin II and III, 2nd Edition January 1939".
As I'm holding it in my hands right now I can assure you that it is not photo-shopped.

Actually I was wrong, the use of higher boost than +6 1/4 was according to this manual not only allowed for take-off but also for emergency.
