Dat 100% timing and tips

so i made a 100% on a unpatched sent using wolivie and wesker’s otg from the berseker
charge and xfactor loop (l,m,l,l,m,l,l,m,l), but the problem is i can just barely get the weapon x timing down after the esker otg, does anyone else have this problem, when getting a otg with wesker to wep X?
