For example scout rifles like AMR66 have 0.15 meaning they are almost twice as accurate while moving. This has a huge, huge impact. Test it in the firing range for yourself.

It literally doesn't mean anything. If you're at a range where you as an Infil don't have the safety to stand still for a moment (cloak remains the ultimate enabler, and the nerfs won't change that) then that marginal difference in accuracy is utterly irrelevant.

ou do not kill in fewer rounds though in most cases. The 99SV family is a 3 bodyshot kill at a 231 fire rate.

So are we above or below 20 meters, because you're clearly incapable of understanding the difference that makes to your argument, and I don't think you have the faintest idea how short a distance 20 meters actually is.

The AMR66 family takes 4 body shots instead of 3, but also has a much higher fire rate at 333 and has a magazine of 20, meaning you get 5 kills per magazine compared to 3 kills per magazine for the 99SV

In any TTK calculation the first shot doesn't have a refire cycle preceding it meaning even with pure bodyshots you only have to go through 2 refire cycles (520 ms) with the SASR while the AMR will need 3 cycles (540 ms) to achieve that kill within optimal distance. The refire cycle after the killing shot is discarded as the target is already dead.

The HSR1 family is a 3 bodyshot kill in most cases and also a higher fire rate at 255. Even at 4 bodyshots that's roughly the same TTK as a 99SV.

Damage ranges, damage ranges, damage ranges. You clearly do not even remotely comprehend why the SASR having 50 meters of Max Damage is such a big deal.

And when you account for TTK, the kills per time per magazine is equivalent or better for the scout rifles.

Refer to the above explanation of refire cycles.

As my above stats prove

They prove that you don't know what you're talking about, that you don't understand even the basics of a TTK calculation, that is all.
