I think your data is inaccurate bro, newer AAM are very deadly, and with AIM9X, and similar AAM, kill ratio per shot will go up. So if you wouldn't mind, post your source, others are welcome to post kill ratios with accurate, verifiable data. I would love it if an aircraft had a 50% survival rate against AAM, but I believe they are far more effective than that these days.
As I pointed out, the kill ratio also depends on the firing aircrafts position and heading and speed in relation to the target, AAM are much more effective off the Raptor due to its high altitude and supercruise increasing missle dynamic performance.
