Ah, thought you were playing around console commands. Sorry, my bad. E-S is the one that modified all the accuracy stuff so I don't know how he did it.
But yeah, don't expect movement penalties to accuracy, ever. Jumping is the only accuracy penalty you'll get that's related to movement. Same with getting kills dealing only a headshot or two with rifles, it'd totally destroy what this is meant to be.
Most of times you'll kill faster and easier with rifles than with a pistol unless they don't move or aim 24/7.
Not to mention that if you shoot fast with the sniper rifle it's pretty hard to hit anything, same happens with most of the rifles at mid range.
When accuracy changes were in development, I requested it to be so the first bullets always went to the center if you tapped or aimed, and that's what we got in the end, increasing the spread way more than what it was before. (Which was completely random and most of times first bullets never went to the center of the crosshair)
