And we haven't even gotten into issues like thermal noise... Who knows, it may be great, but right now it just looks like a press release :-)
Oh the 1/10,000,000th comes from assuming they need to reset 128 * 8000 times per second to merely equal current sensor performance before losing sensitivity to misc losses.
If they want one more bit of DR they need to cycle in half as much time, and so on. Similarly, if we generously assume they're only losing 50% efficiency to cycle time and real estate then double again.
