Second experiment: how fast can a mining chip respond?

My simulation of miners and capacitors needs to know how fast a mining chip can change its power. Nobody has published that measurement, so I am making it on three Bitaxe Supra boards. The power meter has three sensors. Two of them are wired in and checked against a multimeter. The third connection and the chip tests come next.

First experiment: how fast does AI power move?

In September I rented an NVIDIA H100 GPU, sent it requests timed and sized like real chat and coding traffic, and logged its power. In 1 of every 100 tenth-of-a-second intervals, its power changed by at least 36% of its peak. I wrote seven predictions before the run, and four of them were wrong.
