So the OBD had a calculation of Levi in the Varia Arc dodging natural lightning here: http://www.narutoforums.com/xfa-blog-entry/khr-levis-speed.33587/
I'll be doing a revision using the statistics that this site uses for lightning speed. I'll keep the original scaling done the same as well.
Distance between rod and Levi: 1.93 m
Lightning speed: 440000 m/s
Timeframe: 0.00000475 s
Distance Levi jumped: 0.75 m
Speed: 0.75 m / 0.00000475 s = Mach 460.33 or Massively Hypersonic
