So you're advocating that he do a maneuver that will lead to his death 10% of the time, vs. an extension that will lead to his death 0% of the time? 
The 190 pilots who can consistently outscissor a Spitfire are gods for whom I have the highest respect. I've done it successfully and unsuccessfully, but criticizing someone for not attempting it when extending is the better choice doesn't make sense. There are many occasions when a scissor maneuver will lead to death less often than trying to run away.
If your that concerned with living then MSFS might be the way to go. Unless an individual puts himself to the test there is no chance to improve his cartoon plane skills. Face it.... if you do not die much then your not pushing the envelope.
Some of the most memorable fights I have been in were OTD and outnumbered. To get into that situation and actually come out victorious is exhilerating to say the least. My 38 is a large ac and usually targeted in a furball. That to me is no problem as it allows me to hone my virtual abilities.
Rank means very little but many like to track their k/d. On the other hand k/d means nothing if your usually flying around playing airport or only engage when your in a far superior ride/position.
