I think the system is well optimised.
MSFS also has the advantage that there are tools which let you record and play how you have flown. While you play that "track" you fly another aircraft.
That way you can create things like this.
Might still be they did it another way.
It's a pity the aircraft are shown flying line astern. Doesn't look realistic. I don't know the actual dogfight but that doesn't seem to fit with WW2 tactics, be they German or USAF.
