If you quiet your gun considerably and it costs 5 fps, it was worth it.

I doubt you would see any losses with a gun shooting 400 fps, but 250 fps is a tad different.

right there^ just air turbulence on low fps guns. Also often it doesn't line up perfectly, so it makes sense. Its not more then 5 FPS (I assume) really just people trying to sound right because they have knowledge of what happens with real weapons.
