That's precisely what I'm doing, but I'm using the resistance of my source instead of a discrete resistor. Here's a
link detailing the procedure.
Incidentally, we already had all the information necessary to compute inductance. Look at the current waveforms in the original post. During the on-time we apply ~13.8 volts for ~12.2 us and got a delta-current of ~2A comes out to about 84 uH. Of course, I'm not using cursors but rather eyeballing the PNGs I posted earlier, so it's completely expected that the number not come out the same. But it's right ballpark.
