If you use full zoom offline you will notice it appears to give you the tip of the closest wing as the real target that gets hit from a 6 position shot. Once you cut that wing off, then based on the green cross, shoot again, your rounds will pass through the missing wing's old space. Since the drones fly between 225 and 250 around the circle, you are not learning a useful lead allowance for the MA where combat speeds are in the 300-450 range. If you can get a trainer to let you chase them with the LCG in the TA, you will get a better sense for lead allowances.
One of the few really useful things the LCG does, is shows the stark differences in ballistics timing between the MG17, MG13, MG151\20 and the MK108 during lead shooting. The other is in understanding lead related to being higher, lower or head on. Still, it will be at offline speeds and not MA combat speeds.
Or you might see if someone's offline AI mission will allow you to turn on the LCG to use it under more realistic conditions.
One of the problems with the LCG just like pilots in WW2 had once they moved to the K14. You learn to aim to the visual crutch rather than how to aim from a fixed reference. Once pilots got used to shooting with the K14's lead computing reticle, if it malfunctioned and they had to enabled the fixed reticle. Judging lead against a moving target by eyeball became problematic at best for them.
