Shot #1 was bad because it set you up for the next bad move where the F6 nailed you good.
If your high and behind, YOU dictate the fight. Pulling hard to try and get a lead burns E and you still dont get the shot, or you get a poor one. In the first passyou tried to turn and follow the F6 after rich. Had you looped, or high yo-yoed there you would have droped onto his six with more speed and E and had closed.
The next point (your point 1) again, don't blow your E on a bad shot. Had you high yo-yo or looped there he would never had had the E to climb with you and give you the pilot wound. Stay above the fight, you dictate what happens next, take away HIS options.
Your point 2, lucky shot only in that had he not been busy with the other con you wouldn't have gotten the chance for that shot. Other than that it was a crossing shot with a good profile to shoot at and you took enough off him to finish him off.
Your SA is pretty bad, it's what gets you killed the second flight. You can see it in all of your films. You should be looking around almost as must as looking at your target EVEN WHILE FIGHTING. Don't concentrate so much of your target that 3 others guys can creep up behind you. That is what all the good players do. Look for which ever bad guy looks busy chasing a friendly and then pick him. Don't be that get getting picked all the time.
Trust me, we have all been there. It takes time to learn but you'll get it.
