So during my morning meditations I started to ponder the great philosophical question of the age: "What if when a writer uses nano/micro/mille/whatever-seconds they don't mean it literally, or at least not in the way Battle forum users read it to mean?" Then I started thinking about how how street levelers have feats in the nanosecond range that nobody takes seriously, like Iron Fist. But what about characters who aren't street tier? That's when I remembered a funny feat in SW where Talaan catches a blaster bolt, which amazes Luke, in the space of a nanosecond.
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., 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 funny at the time, since there is no way that the author is using nanosecond literally, since that would mean that Talaan and the blaster bolt are both FTL to many times faster than light. Bare in mind a beam of light doesn't even travel one foot in a nanosecond, unless Luke was firing from even closer the blaster bolt is FTL, and Talaan has been calced at twice the speed of light based on this feat IIRC.
For further confirmation we know nothing in Star Wars is faster than the speed of light, and we're extra certain blaster bolts aren't because the scientists who made this droid would surely know if they were.
I-Five stood nearby, aiming both fingers at the prince. "Please shut off the lightsaber, Your Highness," the droid said. "And toss those blasters aside as well."
Xizor snarled, his skin flaming with anger. I-Five's aim did not waver. "I'm sure you're quite fast, Prince Xizor, but not as fast as light." He shrugged. "Universal law and all that."

This got me thinking of another famous nanosecond feat Luke has, where he perceives in the space of a nanosecond (notably, however, he fails to react). From the same novel as the one where a blaster bolt reaches its target in a nanosecond and Talaan catches it.
He had no time to be astonished, barely even the nanosecond required to realize Abeloth had survived her fall into the cleft. He merely felt his feet shoot away and found himself dropping face-first. Luke tucked his chin and managed to flip to his back before he hit the stone floor. Abeloth was on top of him, her flesh blistered and smoking, her remaining leg entwining both of his, her remaining arm wrapped around the back of his neck.
The same writer who wrote the feat of Luke perceiving in a nanosecond also used nanosecond to describe Talaan and a blaster bolt moving, which would almost certainly mean moving many times faster than the speed of light, which is impossible in the verse without hyperspace. Even if you can accept that Talaan and the blaster bolt moved in a literal nanosecond, you'd have to accept that Luke failed to react in the same timeframe when facing Abeloth, meaning that Luke cannot react to blaster bolts. So it becomes a pick your poison situation:
1. Accept the the author uses nanosecond literally and Luke can perceive in nanoseconds but not react to blaster bolts (or at least not unless they have to travel much further than they did against Talaan). Blaster bolts are almost certainly many times faster than light.
2. Reject the the author uses nanosecond literally, meaning Luke's nanosecond perception feat is bunk, but we don't have confirmation he can't react to blaster bolts. Blaster bolts are probably not many times faster than light.
