many moons ago i came upon a similar site but with knight 24s. my jet with full fuel and 30mms.
but cuz of frame rate freezing, i could only manage 6 kills too.
I was helped tho by (as in your film) bad formation discipline. just focused on the edges of the formation. If they had stayed together, i wouldent have lasted 1 pass.
I did notice (with a smile) that you sucked up your gear knowing that wheels up makes for short landing:aok
