The projectile is great, the gun isn't.
Before I get flamed now: I mean that for practical purposes. Slower rate of fire and much less ammo means you really have to 'snipe' - pretent you have a single shot weapon and use it accordingly. That makes it less effective in true dogfights than the Mk 108, despite it's better ballistics.
I actually like the slow rate of fire. In the Mk108 I always release more spuds than I like to and trying to shoot fewer takes to much attention or jumping of the trigger. NS-37 IS a sniper cannon. In term of effectiveness just give me a quad of 20mm, but if one insists on a single nose tater then I agree, the Mk108 package is more effective.

My problem with the Mk108 has always been my lousy gunnery skills. The only way I could make it work is by flying right up to the nme, so close that it feels like I am "attaching" a 30mm sticky bomb to it. The I used to ram 1 out of 4 of the victims. The NS-37 allowed some better shots against non maneuvering targets.

Random dispersion is being reasonabley modeled in the game for this round. Check the last block of data for the dipersion at distance. Note by 200m(219yd) your random dispersion is 14ft.

Dispersion is your enemy opposed to lead timing which for the most part is lead the con 2-3 times as much as you are used to. The game code gives you a gamey advantage to average out random dispersion a bit by allowing you to tilt your gun barrel up inside of the engine out of line with the hollow airscrew shaft. In the real Bf109-K4 the cannon barrel was locked into the hollow airscrew shaft with no ability to elevate the barrel. Rounds could not be fired above the line of the airscrew shaft.

350 yards convergence is the "gamiest best" because it will average your rounds within an almost flat trajectory to 350 yards. Most of your shots against fighters will be inside of 350 yards in the game. Inside of 400 your biggest problem will be lead timing since the round slows down so rapidly. Test this against drones offline. Inside of 400 your shots are mostly point and click. If you look at the 650 convergence you can see past 350 you will progresively be shooting your rounds higher at distance with an ever expanding dispersion cone. There was a reason the MK108 was designed to shoot bombers in real life.

Setting your convergence to 150 is the closest you will get to reality.

I think i took up the Jak9T only a handful of times, my experience with it is very short.
...

 the plane itself is slow and is a poor turnfighter. I would say, practice a lot in the DA til youre confident.

I don't know, I think you may just be a bit outside of your comfort zone with the Yak 9T if you're as used to 109's as you are, spend a little more time in it and I think you'll see it's a nice bird.... the 9U's slightly 'top heavy' sister that may not be as light on her feet on the dance floor but can bring the happy once you get to her "sweet spot"  :) .

The 9T is only slightly slower than the 9U, and the 9u is a race horse, and turns pretty well as long as you keep your -e up.... but isn't bad slow either. I'm a mediocre pilot at best, but I was able to make LA's, ponies, and 109G's overshoot and kill them on the reverses, the LA being a LA5 that took a tater after 3 scissors. Flaps were full out by that point.

35 taters is a very limited load, but it's good for 5-6 kills on 1 sortie with no rearm if you can resist the urge to spray.

Yups, if you can master it, good for you and im just happyer. My brain is pretty simple, only can think in the 109's dimensions, so dont take deep consequences.
With a perfect pilot, the gun alone can make this plane very dangerous. More power for you to master it!

Like, ya know, when that thing that makes you move, it has pistons and things, When your thingamajigy is providing power, you do not hear other peoples thingamajig when they are providing power.
