Having gotten my grasp of the games gunnery physics straightened out now via MtnMan and Morfiend's kind assistance. I've gone back in and pulled data for all of our fighters to help players accomplish seeing the results of their convergence settings as if their aircraft was on leveled static stands at a bore sighting range.
My assumption is that when the center of the aircraft is aligned with the center of the target during auto level cruise, this is the equivalent of placing the aircraft on a leveled static stand at a bore sighting range. Oh,,, and try flying inverted level and test your guns. I hear it's an eye opener these days........
Data Collection Method:Data was collected by flying each aircraft at 1000ft North with the offline Target set between (.target xxxx) 2, 2.5, 2.75, 3, 3.5, 3.75, 4, 4.5. The target command will accept fractions and will display the target down to 1 yard. These small number values made it possible to show a small part of the nose, prop spinner or prop hub through the target on it's back side.
1.} By using F3 mode, zooming in and then the NumPad_Key1 the back side of the target can be observed. As your speed increases the nose of the aircraft lowers.
2.} When the nose/spinner/prop hub was bisected by the target horizontal center line I noted the speed from the E6B. The next step is to return to F1 mode, move the target to 100 yards, make sure the aircraft is auto level at the noted speed or using that speed to make finer adjustments to center the aircraft's nose/spinner/prop hub while using the F3 mode and numkeypad_1 process.
3.} Having made sure the aircraft is at the correct speed, then goto full zoom and note the distance in Mil the center of the gunsight is above or below the target center horizontal line at 100 yards.
4.} Now 2 refrence values have been collected for each aircraft to assist in leveling the plane in it's flight path before testing your guns against the offline target.
Excpetions:1.} The Spit-XIV's Griffon engine is down angled from the center line of the aricraft by 2-3 degree.
2.} The F6F's engine is down angled from the center of the aircraft by 2-3 degree.
3.} The Me163's nose in auto level will not at any speed aline with the horizontal line of the target. It stops at about positive 1 degree high.
4.} The SpitI's level cruise speed tops out at 285 true off WEP which leaves the prop spinner about 1/2 degree high.
I have provided a Mil calibrated gunsight to help in testing your own convergence settings. Copy both files to your sights directory.http://www.mediafire.com/?8705o7b7grhx2a5----------------------------------------------------------------------------
1Mil @ 100yds = 3.6 inches
1Mil @ 150yds = 5 inches
1Mil @ 200yds = 7 inches
1Mil @ 300yds = 11 inches
1Mil @ 400yds = 14 inches
1Mil @ 600yds = 20 inches
1Mil @ 1000yds= 36 inches
---------------------------------------------------------------------------
Note: All WW2 engine mounted cannon were lock bolted in line with the hollow prop shaft and could not be tilted to achive elevation. The closest convergence setting in the game to the gun barrel being locked parallel to the engine line is 150. The game does tilt the line of sight down for the Revi gunsights in the 109's like the WW2 armeror's diagrams. Setting any convergence other than 150 will result in shooting unexpectedly high and a bit gamey since the real guns could not be tilted in the engine.

List of tested aircraft, cruise speed, and Mil number.Mil numbers with a (+) are above the target horizontal red line. Mil numbers with a (-) are below that line. The number zero(0) means on the line. Use the E6B from the clipboard when adjusting your rpm's and throttle to achive (xxx) true speed while in auto level.
