What a tracer should look like (before spazzing just look).

I'm getting personal because no matter what I show or tell you, you still don't listen.

Take a light source, say a laser pen light with a room full of smoke and point it towards something 5 ft away in a fixed position, so you can see the beam of light. Now have this light pattern repeat very rapidly. As this light source is switched on and off it will not matter one IOTA where you are standing or viewing the light. It will always be in a straight line UNLESS, you got hit by a freight train or decided to pull a few G's out of your butt while standing still. Your eye's WILL ALWAYS SEE THIS LINE AS STRAIGHT.

That is simple physics. You may see the line shorter or at a different angle depending on your viewing angle but viewing the trajectory of said moving object that produces the light trajectory will always be viewed in the in the same direction and trajectory that said object is traveling. (UNLESS as stated above)

If you can't understand that, then you need to take a remedial science class. Or you could quite simply fire and observe 1000's of rounds of tracer ammunition from fixed and high speed moving positions.
