Flying with tracers off will force you to learn how to lead with your gunsight rather than with your tracers. It usually takes about a week or so to get used to having the tracers off.

I agree. Just as turning off your gunsight would force you to learn how to lead with your tracers rather than your sight. I just don't see the benefit to learning that is greater than using your tracers. From a technical standpoint, your sight only shows you where your bullets would hit if you fire while your wings are straight and level, at 1G, and fire at a target at the same distance as your convergence. ANY deviation from that will make your bullets hit somewhere other than where your sight would lead you to believe. So for the vast majority of shots fired in the MA, the gunsight is not telling the "truth". Using your sight while inverted, for example, should make your bullets hit 6-10 FEET low, even "at convergence" while using the tracers to direct your rounds onto the target still works fine inverted...
The tracers still give a basic idea of where your rounds are going, regardless of your planes attitude, G-load, etc. This would seem to show the tracers should be more helpful than a gunsight.
I actually tend to ignore the sight AND the tracers while I shoot, and concentrate on the target instead. When I have trouble hitting, I tend to watch the tracers and adjust accordingly. This seems to work well, especially considering I generally need to move my sight OFF the target in order to get my tracers and other rounds ON the target.
Interesting discussion...
