Go offline and take up a spit16 with conv 150, 250 and 300. Get behind a drone and equalise your speed. On zoom at 200-300 shoot them down but, only account for lead not eleveation. Just place the center of the gunsight in line with their wing line and hold inside of their turn. Your rounds should fall short in a curve following the line of the rudder to the tip of outside wing at 300(Icon 400ish) and as you get closer 200-100 the stream pulls in and some will hit. Now repeat but, raise your gunsight center about 12-14Mil doing the same thing. Now you are compensated as you pull the trigger you start out with rounds on or very close dropping into the target not fishing around to get rounds near the target.
Everyone learns to shoot in the game by fishing around with the tracer stream once it's on it's way. When you compensate then you start out with your stream on the con or so close you stop giving the con the time to evade your gun fishing expedition.
Your armorer would adjust the center of your gunsight after your guns were set for elevation, then crossing convergence to achive the best shot pattern at expected combat distances 200-350. Your armeror adjusted your gunsight center so you could generaly place it on the con at the 200-350 and not have to remember to always hold it a bit higher when you pulled the trigger like in this game. Becasue you had been trained how to judge distance by fractions of your main ring you knew when to open fire between 200-350 where your armorer had adjusted the center of your gunsight. Hitech takes care of the range with the Icon.
This all seems like: Well Duh man how obvious can you get......
Having a line to hold you steady as a refrence point on zoom helps you to not fish around and guess so much. Then there are players like MntMan with lazer guided eyes.
