Thats realy necessary since the running speed was increased in PR. Bevore it was acceptable but, since this patch from PR the dust effect is a regular situation. You cant hit running targets properly. QRF made a video of that a long time bevore.
If this fix is compatible it would be great!
So to lower the deviation and made PR more action like to counter this problem is in my opinion the wrong way. It would be better to fix this problem with your fix.
To lower the deviation and centration of a gun made the attacker become more stronger. This lowers greatly slow movement and static behavior tactics, what in conlusion lowers tacticly movement and teamplay.
If someon is static he should be way accurate then someon is moving. So that covered movement is necessary and still effectiv.
In 95% of every casual game the attacker is in most situation in advantage. Like that is the gameplay running and spreading, die spawn die spawn die spawn.
It should be clear that respawn times of vehicles/players and weapon behaviors can have major consequences on the gameplay and playstile of Project Reality. Changes here should be double checked and multiple side effects considered.
