Here is the source document for this quote. ...
Already posted in post number two in this thread.... This might be more readable:

It would also appear to be conditional on Auto Prop pitch installation.
I disagree, quite clearly its not conditional to whether auto prop pitch was introduced or not. The situation was that APP system was not yet set up to maintain anything more than the nominal max. rpm. There are some promises that at some later stage the settings of the auto prop pitch will be modified to ease the burden on the pilot by taking care of the maintaining the increased rpm ratings automatically. Until then pilots had to revert to manual prop pitch control.

IvanK that's the (in)famous document, may wonder about the date added by pencil. To me it seems that even if the date is post-BoB, the practice of overreving the engine above FTH was common during the Battle. Steinhilpers quote for example is dated 27.10.1940./QUOTE]

Agreed as well. It seems to me the RLM merely sanctioned a long existing practice (given that mechanically there was nothing to prevent pilots from overrevving anyway).
