I've never seen him to that. Luke does have some crazy ****ing feats though.
No way is he mach 1000 though. They say that a nanosecond was considered slow to him during that Abeloth fight but I've also never heard of that. I guess I could check it though.
'Luke pressed the trigger and held it down—then felt his jaw drop as bolts began to ricochet off the High Lord’s palm. It wasn’t the deflection of blasterfire with a bare hand that shocked him—he had fought plenty of Sith capable of that trick. What amazed Luke was the speed with which Taalon had moved. In the nanosecond it had taken the first bolt to cross the distance between them, the High Lord’s hand had risen to deflect it, traveling so fast that the appendage had literally seemed to disappear from one place and reappear in another.'
I found this. Luke reacts with amazement at that level of speed.
Couldn't find anything else.
