I can concur on this behavior. I'd say roughly half of my kills with 37mm are these poor chaps. I have noticed it's the same 50 or so people doing it over and over and over and over. The reason this behavior seems so prevalent isn't because alot of people doing it per se. It's because the 50 or so that do do it, seem to do so 20 hrs a day to the almost total exclusion of any other activity. They almost always die in the process and usually fly an La7 or similiarly fast, quick climbing plane so you can see them do it 3-7 times an hour...
The really sad part is, being a statistics nut, some of those that do this are, supposedly, if you believe rank, some of the top 100 fighter pilots in the game...So, one could conclude it's not your fighter rank that indicates any talent, but instead how you achieve it, which unfortuantely cannot be quantified statistically..
