I'll tell you what I did to get a noticeable improving in my gunnery effectiveness:
1. Go to the MA and fly as usual. Film every sortie.
2. Then watch the film.
The important work here is JUST study the "firing style" you used for those enemies you shot down through your most "
usual and successful way" for shooting them down. Just study your perfect kills, you must have one here and there..
3. For those "
your often personal-style-perfect kills" speed down at minimum the speed of the film, and watch in the right window the
EXACT distance you started to fire.
4. Set the convergence for that distance.
By this methods you are setting your gunnery to the situations where you shoot the most, and when you get your kills in the easier more personal-fit ways.....
Once you have set your optimum convergence for
your optimum way of killing enemies. You must work further and further of this optimum point. Then you have to decide if it is still advisable for you or not, shooting at the enemies at those differents distances.....
Example:
Studing my more comfortable and common kills in the films, I found out that I start shooting enemies over 150-250.
So I set my convergence to 225. After doing this, I started to literally go the tough hogs off with just 0.5 sec burst.
After studying this convergence that works fine for me, I realized that shooting planes closer than 225 is fantastic as well. So I will go for every manoeuvre that puts my plane between 50-225 yards for a devastating shot.
Also I realized that, with this personal convergence, shooting enemies within 300-400 range won't work UNLESS they are flying very steady and I can get a 1-2 secs solution on them. So with my style and personal convergence I will only shot planes further than 300 if I'm pretty sure I can hold them centered about 2 seconds.
And I have discovered, that, shooting further than 400, won't hurt much planes. SO I don't shoot them at these distances and I'll try to fly my plane to get close to the enemy under my personal range.
So, my suggestion is: Study your convergence for your style, and then, study your style to maximize your convergence.
