the difference is 80 ohms. that's hardley a difference?
we used to shoot for ~ 200 ohms...we're talking 570 vs 650 ohms now. (when I say "we" I mean those of us that attempt to follow you on power supply design)
if you do believe in using the step response then surely the math that is used to evaluate it is relevenat?
or are we just looking at DCR and using step response to show the smoothness of the waveform?
all you're doing is comparing "under dampened, over dampened and ringing power supplies". (from the JLH documents you sent me)
also, do these 1H 9.5 ohm chokes really exist, or are you manipulating the inductance to get the results you are looking for? since you are now locked in at 30uf and 50uf, all you can vary is the chokes?
