Hi Vermillion,
>Prove it.
Price' book proves that the Luftwaffe's Sturmgruppen had specialized (and non-standard) gunnery circuits. Reschke's book proves that the Sturmgruppen fired the different calibres individually in combat.
>I have direct information (a detailed pilots manual) that I have posted here that says it does NOT work that way.
You have posted one standard configuration here that is not even Rüstsatz-specific. It also looks like your "pilot's manual" is in English, and as far as I've seen, it doesn't quote which original Luftwaffe documents (if any) were used as a source. The way Luftwaffe documents are organized, the complete description should be expected to be part of the "Flugzeughandbuch" ('Aircraft Manual', not pilot's manual) which actually consists of a series of individual booklets on the specific subsystems. The booklet on the barrel armament ("Schußwaffenanlage") would contain detailed and specific information on the standard configuration of each of the Rüstsätze instead of the generalized statements on the pages you posted.
In short, your "manual" can't be expected to provide a final answer to the question. Needless to say, discounting (or actually ignoring) the accounts of operational pilots isn't a good idea if all you have is an incomplete manual of undocumented origin.
It may be interesting and even fairly useful, but it has its limitations, and I'd suggest to try and stay aware of that.
