35 scapls in 30 minutes would indeed be an awesome result. Only very few pilots can do this. We do have one or two with a K/H of 40-60 in fighter mode each month, but those usually did only one single sortie with 1-3 kills.
But let me take the hypothetical numbers of yours and see how that pilot would have ranked in tour 153: If we assumed a top notch hit% of 15 and the average number of points per kill, he would have ended up at rank 56.
The sub-ranks:
k/d 5
k/s 1
k/h 1
hit% 34
points 988
The supreme k/d, k/s and k/h results are more than offset by his lack in kills.
Well in my example, he has 35 kills to the 1 death the HTC adds, his kill per sortie would 7 (5 sorties 35 kills) his kill per hour would be 70 (35 kills in 30 minutes) and his points would 988 we'll say.
Granted those numbers are pretty wild, but for a good pilot easy enough to get catching a few NOEs and popping low slow planes. Now if he did this at the beginning of the tour and never flew another fighter sortie how would it pan out?
It's a pretty darn good starting point and would rank him very high that first day. With many others flying lucky runs a single sortie with 5 kills say, or a couple with a few more would be the only guys who would come close in ranking. Now if he didn't fly any more sorties, all of his number would stay the same for the month. Other pilots would have to have unbelievable runs to catch his kill numbers but would easily surpass his kill points.
Is that how it would work or am I missing something? Your charts show it isn't rampant, but that doesn't mean it wouldn't work.
