EXACTLY

That's EXACTLY what I saw when firing tracers with a WWII design AA 20mm canon.

Sitting directly behind the barrel, sure.
Throughout my tenure in the Parachute Infantry (and then Mechanized), I was a SAW gunner, a 60 gunner and the 240 before I was a squad leader.
Anyway, the tracers from MY weapon appeared as dots but those from my soldiers on the flank or next to me appeared as streaks and turned into dots as they were further down range.
