When has any of those blasters ever shot with a speed of Mach 8? How about NEVER. And did Obi-Wan actually deflect every shot from 10k droids? NO. You know what he did? He deflected only the shots that would hit him while he moved. That would be a Fraction of those that were actually firing, and we know from experience that Battle Droids are effing Terrible Shots. They're about as bad as Storm Troopers in the Movies. And we know explicitly that blaster bolts ain't anywhere close to Mach 8 because we've seen Clone Troopers dodge and avoid getting shot.
capable of deflecting blaster fire from over 10,000 droids firing semi to fully automatic blasters that was calced between low end mach 1000; very conservatively to mach 16,000 with mach 8 blaster speed
There's such an abundance of exaggerated BS when it comes to Star Wars that it's even worse than what people have spouted about DBZ.
