In a nut shell I'm saying K/D means jackdoodlysquat
I don't know if I agree that it means "jackdoodlysquat". Not every two weeker can post up a >1 K/D in a tour. But I do agree that it can be manipulated pretty easily. Heck, fly a P51, 190, or Typh in full high alt BnZ 1 pass extend 6k pick mode and just about anyone can put up a good K/D ratio. Which is why, I believe, we see the large numbers of runstangs and run90s in the MA these days.
I personally don't see the appeal. I've flown that way before, in the P51s and 190s, I never make it very long before I get bored and up in something a little more interesting like a Ki84, 109G14 or F, F4U1D, or maybe C205.
All that said, I am wondering if there is ANY metric in the current score system that has much value in judging skill? Seems like they can all be manipulated to some degree or another.
