Stats I can probably get and hold a 10 to 1 K/D if i flew a tempest and flew it "smartly"
And your stats would tell us that you did exactly that.
Score & Stats often (not always) actually can tell us about a player... if you take a look at the whole picture and are not staring at the rank # or the tremendously overrated K/D ratio alone.
The example Akak presented is such a case: You only are tempted to say "wow" if you don't notice that this very player did fly one sortie in fighter and all others in attack mode. That completely changes the picture, and this we can tell just from his stats.
A high K/D but a very low K/H indicates a player is spending a lot of time looking for opportunities and doesn't hurl himself into the next furball. Has he lot of bomber kills and a relatively high hit% too? In that case you can see he's a bomber killer, crusing at high alts.
One tour I had a very good K/D and k/H... but you could easily tell how that was done when you noticed the fact that I had ~90% of my "fighter mode kills" in 262 and 163, and you could see I was for the most part just slaughtering buffs, which put my "good" score in perspective quickly. All that you could easily deduce from the stats.
Stats can tell us a story... just put them in relation to each other, and don't let petty prejudices take over your judgement.
