Yes you where stick sturring. But nice shot.
No, he wasn't stick stirring.
looked like decent evasive maneuvers
But I wouldn't call them decent.
Stick stirring is what happens when a complete noob thinks that spinning his joystick around with the goal of just making the plane "flop" all over the place is how you avoid getting hit.
Stick stirring relies on pure luck and technical loopholes to survive.
What you did were purposely executed moves meant to keep you out of his guns, but they could have been better planned and executed and you could have force an overshoot rather than simply hope that he didn't hit you as he closed in on you.
