I have the film recorder running on most of my engagements, this way i can look at the film later if i find something weard. Often i got shot down by a second plane that i did not see, had two on my tail instead of one.
On your problem hitting, my girlfriend is flying too so we sit next to each other, sometimes we go into dueling arena or open h2h. I found out that hits on one site are not necessarily hits on the other side, so when a tank fires on another tank in close range with the mg for example, sometimes you would fire on a place nearby instead.
Second, a hit percentage of 60 percent in a dofight is insanely high. I dont beleave that.
Third, when you fly directly behind a buff put in good sideslip, hard to hit.
Fourth when you are blacked out half of the fight you dont see what the other guy does during that time AND loose lots of E. Its hard to outfly 2 spitV but when both are blacked out half of the time that is no better than one.
Fifth cal .50 and smaller mgs have the problem to cause damage only when you get a lot of hits in one place. Verry well possible for a P47 to get sprayed all over and not sustain damage, because the spit fires only 2 cal .50 which results in a good distribution of hits.
One more, i am not sure if every round is a tracer..maybe someone can confirm or deny this but i think on MGs only every 3rd or so is a tracer?
That would mean if you see hits for 60percent of the tracers you see that is only for 20percent of the bullets you fire.
So on your behalf i want to say that some hits on your front end are "fake" hits that would not have happend if there way no network lag because the guy is somewhere else than it appears to you. So your right, sometimes you see hit sprites while there are no hits.
