Gunsight Setup
Accuracy is relative in this game depending on who is teaching you gunnery. At one extream you will be taugh to use a large dot, never use zoom to close off your periferal vision, and shoot at very close ranges to ensure you won't miss. This will require learning ACM very well since your con will be seen in an area smaller than a quarter(.25$) on your monitor. Another group will teach you to use zoom and take advantage of traditional shooting techniques of Low E Angle Off shooting based on a 100Mil main ring relationship to angle of relative travel. This will enlarge the 100Mil ring to about 3inches or what the pilot actualy viewed in WW2. Then you will use percentages of the main ring diameter for your holdoff dependent on the amount of E in the turn or the relationship of the cons tail to it's inside wing.
In both of these cases you will have to learn by trial and error how much elevation to apply to account for relative forward motion. On a dead 6 the con will not be where you place your pipper and pull the trigger (.14 -.2) second later. Verticle deflection and forward relative speed will cause your round to pass low of your target unless you add negative Mil to your impact point. Raise your nose a tad. (Positive Mil is above the center of your gunsight, negative Mil is below.) I watch players on full zoom all the time aim dead on from a cons 6 and shoot short becasue they don't realise level dead 6 at 1 Gravity still needs a forward motion compensation with elevation of about (-10 to -15Mil) to hit where your con will be at 300mph between .14 and .4 sec from now. Rougly about 2-3 plane lengths ahead of your con to hit it continuously at 300mph over .4 sec of travel. But, if you just out ACM the other guy and shoot from say 100 and closer it dosen't matter becasue your guns dispersion will hit the con if you aim more or less dead on.
Hitech programaticly takes care of aligning your sight line to your chosen convergence. The only thing after that would be you going offline and flying your plane on auto level at about 300mph. Set the target to 100 yards before your convergence, at convergence, 100 yards past and seeing your dispersion patterning.
You might perform the same tests but angle your wings 45 degrees and hold the pipper on the target center to see your dispersion in one snapshot of time while in banked pursuit. You can even set the center of the target up or down by one degree at those distances to see where your rounds will strike relative to forcing your nose attiude held up or held down.
If you build your gunsights in 512x512 format then 1Milliradian will equal 2pixel. Then you can construct your main circles, main rings, 100mph ring in diameters that you can use to tell range by known widths of aircraft wing spans.

A6mx - 12.00m----87---43---22 <--- you can see why the Navy Mk8 gunsight has a 100Mil main and 50Mil secondary ring.
Ki61 - 12.00m----87---43---22 <---and looking above why japanese gunsights have multiple rings 100\50 and son on.
Ki84 - 11.23m----81---41---20

Main rings for fighters during the war were 30, 35, 50, 70, 100 and 105Mil and combinations depending on the country.
Find a copy of AAF Manual 200-1 "Manual for Fighter Gun Harmonization" if you realy want to get scientific about this with formulas and data. Then you can look at some of the same data and math Hitech may be referencing for his gunnery calculations.
So what exactly do you mean about better accuracy??
