Very early in a tour, where you might only have a handful of kills, a single disco can really trash ones K/D. Later, when you have several hundred, it is a minor factor. Fortunately, I have had only one disco so far, and that one was induced by taking a screenshot in flight (or in this case, while in an Ostwind). Unfortunately, there is no easy way around the effects of a disco. They must be factored to prevent people from avoiding death by simply dumping out.
What I find strange about the scoring system, is guys with a much lower K/D being ranked above pilots with much better K/Ds. That's because kill per hour and kills per sortie are factored in without using deaths as a sufficiently important denominator. Again, that tends to promote "gaming the game", rather than encouraging smart flying. A perfect example is below. The first set of numbers are from the #1 ranked fighter pilot, the second set from the #5 ranked fighter pilot... Go figure. But, that's the system, and there's no system that can be perfect for all circumstances. I do, however wish that it placed greater importance on surviving, allowing reality a greater significance in game play. Other opinions will certainly differ.
