@joseph619: You're missing the point. Timing lightning like that didn't make them lightning speed, as you can see in the calc it merely put them in the triple digits hypersonic +, lightning moves at mach 58 thousand, which is FAR above the calc. So it's not a trick, it's a legit scale.
@ohplease: I doubt it is, but let's agree to disagree :P
Probably although I doubt that they'd stand there long enough for the Path to absorb them. They huge amount of chakra probably makes it near impossible anyways. Sasuke was able to absorb Naruto's chakra even though he was using the tailed beasts, so it seems quite possible.
