Tracers or not?

[revi]

I've tried to find the article I read, but no luck. I'm sure there was mention about the velocity of the tracer bullets at impact range had something to do with decreased damage.
I am refering to the .50 browning.
No doubt the inability of enemy pilots to see the tracers would've helped keep the all important factor of surprise.
One more thing that I remember reading was that at the end of the loadout they used to have 5 tracer bullets in a row, this was to indicate to the pilot he had run out of ammo.
But also let the enemy know that too.
I think it would be interesting if we could disable tracer bullets in game, and have the upper hand on the AI.
