Stanton Friedman shreds such equations with humor and wit. There are so many unknowable variables, the equations, essentially, are absurd nonsense.
Of all the ET proponents, Stanton Friedman Is about the best, though usually the shows he agrees to go on are jam packed with some of the worst tin foil hat folks. BTW..... Friedman looks a bit like some of the media representatives of what ETs look like. Hope he doesn’t take offense at that.
