Ive had some hard times against guys with terrible rankings so it goes to show you rank means nothing.
On the other hand when you see someone barreling down on you that you know is consistently top 10 it does cause a bit of pucker.
When I was in USAF I had it explained to me many times why American pilots are so good, and NATO is so dangerous in air power. Pretty much all NATO countries are the standard of air power. Its because they put gas in the airplanes and fly them "all the time". I remember those guys flying those Phantoms 4,5,6 times a week.
And no doubt AH is no different. Put someone behind that stick enough times and they are bound to get good.
