You're using .9w5 drivers right? Isn't that a lot harder to aim coz of low input lag/shakiness? Try .10 or other ones and maybe it will help your aim...
I tried higher driver version but delay is kill...... can not FC 4~5 star jump maps lol........ I'm using 6.3.9w3
but the guy at #2 until #14 with the same mods and same acc get same score. but he get a little more score than the others who get the same acc and mods like him. sorry bad english :(
