A very interesting read! But I was hoping he would explain a mechanism behind the variation. Also, he describes using pulsed measurements in order to minimize heat buildup and therefore the confounding influence of Tcr. I wonder how much of the resistance reduction could be due to capacitive effects - that would indeed lower the effective resistance on a short pulse.
