For what it's worth, they have a graph of a test of a 2 (!) cells at [1]. From a sample of two, it is quite extraordinary, indeed. I find it very hard to believe in the Altair->Microsoft hypothesis. Altair to microsoft was a new practice overlooked by the big guys. Lithium charging is a very concentrated area of research with lots of investment.

For comparison, I found [2] which is a test done of pulse-charging by Electrochem/ENREV and a university. This area of research has been going on for almost two decades. I've found a number of studies on the topic. [3][4][5] I don't have time to analyze them all today, but #5 looks really good at first glance.
