Help editing Pean's AHK MultiScript for smoother recoil control.

Hey MPGH,
I very new to AHK and was looking for help with one aspect of Pean's Multi script anti recoil.
I'm currently trying to add more movements to the AK-47 anti recoil to apply a smoother anti recoil. I managed quite easily to add the extra movements by dividing the original movement by 2, as seen below.

ORIGINAL:

sleep 50
GetKeyState, state, LButton
if state = U
break
DllCall("mouse_event", "UInt", 0x01, "UInt", -4, "UInt", 7)
sleep 99
GetKeyState, state, LButton
if state = U
break
DllCall("mouse_event", "UInt", 0x01, "UInt", 4, "UInt", 19)

MY EDITS:

sleep 50
GetKeyState, state, LButton
if state = U
break
DllCall("mouse_event", "UInt", 0x01, "UInt", -2, "UInt", 3.5)
sleep 49.5
GetKeyState, state, LButton
if state = U
break
DllCall("mouse_event", "UInt", 0x01, "UInt", -2, "UInt", 3.5)
sleep 49.5
GetKeyState, state, LButton
if state = U
break
DllCall("mouse_event", "UInt", 0x01, "UInt", 2, "UInt", 9.5)
sleep 49.5
GetKeyState, state, LButton
if state = U
break
DllCall("mouse_event", "UInt", 0x01, "UInt", 2, "UInt", 9.5)

I did this throughout the entire AK-47 Anti Recoil, however when i tested this i found that the recoil did not match the in-game's speed although i also applied the same math to the Speed values (99/2 = 49.5). is there something i've done wrong or missed?
Friendly advice would be much appreciated as i'm only new and still learning.
