Guns on the La5n

[Sorrow[S=A]]

Okay, this may be something I have never heard of before, but were the shVAK cannons on the La5n reputed for their incredible spread? I ask because I did some testing off line today and I swear those 20mm have a spread of darn near half the upper portion of my gunsight.
Using max zoom I fired on the runway both in bursts and in steady stream. Discounting "falling" tracers in the background on my 1040x780 screen the shVAK cannons had a spread of approx 2 centimeters from their centerpoint. the FW190 was a spread of approx .5 centimeters, the hispano .75 centimeters and the 109 about .75 centimeters. I tested all using only the Cannons no machine guns.

 2 things confused me, the La5n has a huge spread compared to the others, it can be almost anywhere in a 2 centimeter range of where it is aimed. The second is that the FW has a noticably smaller spread than the 109. Didn't they have the same cannons? I guess it might just be the amount of fire from the Fw tricking my eye.
 One other wierd thing, none of the other cannons I tested had a noticable sideways dispersion. Most of theirs was up and down. The La5n has it all over the place.

Surely you noticed it Leonid, you fly this plane more than I do!

Well, consider this observation.  Each plane that you state has a wider spread also has guns that originate closer to the pilot's view.  This allows the pilot to see a truer path of the guns' trajectory.  As the guns are placed wider (along the wing, etc.) the visual path diverges from the pilot's origin to an increasing degree.  The resultant trajectories of said rounds may appear to be tighter, because of the increased angle of the rounds from the pilot's view.
