Looks like he is using TR in 6-axis mode. Maybe with the Z axis turned off.
The last two kills were aimed by pushing his head out against the "buldged" canopy and essentially aiming with the MG151\20's tracer stream. Just like many do with the wirble. Never thought about doing it that way since I only use 2-axis mode to inherit my saved head positions from the hps file. You can tell it's TR by the view over his shoulder which can only be accomplished by turning your head that direction while leaning back against the opposite buldged side of the canopy. The view point then looks like he is looking in from the opposite side of his canopy up and over his shoulder. Anyone with TR in 6-axis mode does this.
If you use only the 20mm for snap shots and deflection shooting you will hit more often and not waste the 30mm which he seems to save for 6 shots. He also understood his lead allowance when he made the almost point blank shot on the bottom of his dive leading by only the very bottom of the Revi16D reticle that was showing at the very top of his reflector plate. That nice reticle looked familiar.....
Using only the 20mm your shooting deflection shots should be exactly like any 190. Offline turn on tracers, set the alpha slider all the way to the right to turn off the gunsight in your 190. You will see it's not that hard to shoot using the tracer stream which he had turned on.
