I said that when I see the entire top of an open top GV covered in hit sprites and I'm firing multiple heavy machine guns and or cannons at a high angle of attack I would expect to see results, but often don't.
Because, maybe you didn't land any sprites on top of them, despite what you think you might have seen? Ever consider that possibility?
I know immediately when I miss, I can see it easily
Don't count on it.
Many people claim on what excellent observations they make, until they are proven wrong by actual footage/recordings of the said incident..
Try remember the "50cals can't kill acks" fiasco on the boards. They came to the boards and exclaimed that it must be something wrong with either the acks or the 50cals. Not for once, did anyone ever admit the possibility that they were the ones who were wrong, not the game.
It wasn't until controlled tests and recordings proved that they were utterly wrong. They were firing hundreds of rounds, yes... but did they land hundreds of rounds? Contrary to what they were claiming, nope!
There's a possibility you might be experiencing the same thing.
I never said I was a deadly infallible expert at hitting them.
True.
But you're absolutely convinced that what you're seeing is always coherent with what is actually happening, which I, seriously doubt.
Believe me, I've done a lot of close-range anti-GV runs and pin-point strafing runs at low alts. In such runs, things are never just what they seem.
You can swear that you're landing good 23mm shells on that Panzer, which seems to just shrug off every attack. You think something's wrong with that Panzer.. maybe lag or something.
And then, what happens is that when you check out the film recordings later, you will ALWAYS realize in embarassment that you were seeing things wrong. This happens to everyone all the time.
So, again, I suggest a controlled test. That'd be the fastest and easiest way to prove your point.
