Last question: the speed of lightning that VS Battles (and i suppose by extension here) accept the one that's used by Harvard(?), right? The one that says something like "4.4x10" plus the 5 next to the 10, which i think reads as 440,000 m/s?

I heard that we currently accept it as MHS+, but what scale in terms of Mach? May i ask that, if you don't mind?
