BF4 AEK Logitech Macro Help

Hi guys

here is my logitech macro I use for aek-971

EnablePrimaryMouseButtonEvents(true);
local recoil = not true;
function OnEvent(event, arg)

if (event == "MOUSE_BUTTON_PRESSED" and arg == 3) then
recoil = not recoil
OutputLogMessage("SCAR-H + RDS + AngledForegrip + comp or suppressor", 2014)
end

if IsMouseButtonPressed(3) and recoil then
Sleep(1)
if (event == "MOUSE_BUTTON_PRESSED" and arg == 1) then
Sleep(50)
ReleaseMouseButton(1)
Sleep(50)
MoveMouseRelative(-3,37)
MoveMouseRelative(-2,0)
Sleep(50)
ReleaseMouseButton(1)
Sleep(50)
MoveMouseRelative(-1,18)
MoveMouseRelative(-1,0)
Sleep(50)
ReleaseMouseButton(1)
Sleep(50)
repeat
MoveMouseRelative(-3,18)
MoveMouseRelative(-1,0)
Sleep(50)
ReleaseMouseButton(1)
Sleep(50)

until not IsMouseButtonPressed(3) or not IsMouseButtonPressed(1)
end
end
end

while it is average, I don't really know what to fiddle with. Any help is appreciated
