Bullet For My Valetine - Scream Aim Fire (Rocksmith 2014, Rhythm WIP)

Can't play it cleanly, just too fast... practiced up to 88% (seemed to be getting near my limit where I can play it clean) speed in riff repeater and then it bugged out and played at full speed so I thought I'd record it... recorded a few times actually, and this was the best of them.
I'll try to improve but I'm not sure what I can do (except just play a lot more) to improve my right hand speed/accuracy, which is really the problem with this kind of music, rhythm wise.
