There is a HUGE difference in accuracy using both methods. Try it yourself.
It IS gaming the game. It would be another thing if you use your MG's to get a read on the Con and follow suit with cannon.
I know folks would get pissed, but sometimes the truth hurts.
Pissed? Hehe, why would anyone be pissed? And who in your opinion got pissed because of your comment in this thread so far?
There just isn't any logic in your argument.
Yes, there are a lot of firing situations where there's a difference in accuracy but saying that firing cannon only is "the only way to get accuracy" is not true, and that is what you claimed at first. But most of the time, at least the firing positions I try to get to when using 30mm, there really wouldn't be much difference if I was firing 30mm only or all guns or if I would have tracers on or not. At point blank range those things mentioned don't really matter. Most of the time with the 30mm I try to setup snap shots where the target flies through my gunsite at about 20-150 yards at very high deflection angles. At situations like that the firing time is so short that you have no time to correct your aim anyway. On straight 6 shots with 200-300 ranges, yes it is best to fire cannon only so you can use its tracers as a guide.
Again, I repeat, saying that firing the 30mm only is "gaming the game" makes no sense. The real plane had one trigger for mgs and one for the cannon, it is actually more "unrealistic" to fire both using the same trigger since there normally were no such trigger in the real plane.
