Hmmmm...

Low end for Lightning speed is 10^5 m/s or 100,000 m/s is around Mach 293.866...

The Average (which is the one you mentioned in you post) is 4.4X10^5 m/s or 440,000 m/s is around Mach 1293. This is the value that is accepted at VS Battles for calcs...

And Finally the High end is 14x10^5 m/s or 1,400,000 m/s is around mach 4114.137...

These are the typical speeds of lightning in mach... The return stroke of lightning is of a very different speed though. That one is around 100,000,000 m/s or around mach 293866.995...
