Hmmm, seems AWFULLY nonlinear! 13 mils is good for one amp, but you need 173 times more for 10 A? I find that hard to believe, unless this was done at RF frequencies where edge effects dominate. I've been building servo amps and such gear running 10 A on roughly 250 mil traces (1 Oz Cu), but that is low frequency.
