Snail, not really. I know "players" with amazingly high K/D (10+), yet when it came to 1v1, they "tryed" to run to their CV ack in a zeek from a just upped Lala or in a ki84 from a Dora. No kidding!! If this says something.
That you know someone who can do this doesn't mean "anybody" can. I have seen somene killing late war planes left and right in a C202... does that mean anybody can do that too?
The skill level of the average player is often vastly overrated in such discussions. The majority of players in any give tour would be hard pressed to get 10+ K/D in anything, no matter how hard they try (=how 'cautious' they fly).
Their aim isn't up to par, they can't identify the opportunities to rack up easy kills on the map, their SA sucks so they will get picked at some point, they crash next to the runway while vulching (heck, even I do that), and so on.
While I'm not claiming somone with a k/d that high is automatically among the 'top pilots' (however subjective that is), it still takes skills not possesed by the aforementioned "anyone". The average player can be glad to get a kill every few sorties and sometimes even getting home.
