Aww don't take the insults too seriously. I've already asked you to show films of your claim that so many fights occur over 15k... your answer is what, to ask me to post films? lol.. maybe you should follow your own council and get a grip. 
Were people to care enough to spend a minute to post, they'd tell you the same thing I'm telling you: almost all kills occur below 15k.
Think about it: If I'm successful at getting kills below 10k, who am I killing? In other words, in order for me to get kills below 10k, there must be people there to kill.
Now, I get about 10 kills per hour, which is by no means exceptional but it's not on the low end either. Obviously there's plenty of targets below 10k.
Where they die and where they fly, are two different animals.
I am not asking for films, I am asking for you to prove your claim that
1% of all
fights occur at 15k+, Kills are another thing and usually result from them coming down from those alts and would die below 15k, but the fight started well above the alt they died in.
since I already know that when I fly against Rooks in particular, that this alt if not more than 15k is the usual alt you encounter them. 15k is usually just at the cloud layer, and thats where I have to go to get to them and many times they are well over that and I still have to climb to get at them.
If you had said that maybe 10% of fights were at 15k or above, I may have bought that, but not 1%.
I very rarely see a con above 12k anymore.
Now, while we're at it,
Well, here's the problem with the above quote. I have flown for every country for extended amounts of time, and honestly, I see more Bish in the nose bleed sections thatn I do Rooks. Don't take offense to that (since I know you fly Bish only), but this is an observation I've made in my AH career.
No offense taken, but yes I for one have been flying higher since that is where I have to go to get them or find myself getting picked from ones that are at those alts.
