nope he just uses loads that have remote sense (Chroma) along with ones that don't have (Array) and apparently he doesn't utilize current shunts for the latter along with a measuring device (e.g. labjack) in order to measure the correct DC Watts. To do so he would need, besides the corresponding equipment, a custom made software that takes input from the non remote sense loads and the current shunts and add the calculated load to the one that Chromas read.
As for the lower ripple, if the difference was 10-15 mV I would say that this is mostly because of the high temps in which I test and many times the higher the temp the higher the ripple is. But a difference of 30-40 mV is just too much.
Anyway, my main objection in his results is the efficiency readings since I may got a bad sample, ripple wise (although Wolf had measured also around 60mV ripple so I don't think that this is the case).
