I agree with the comments on measuring the inductor current, a fluke 73 probably isnt going to do that well, most meters like this use charge balancing conversion techniques and are not designed to measure high frequency or complex waveforms, the meter is more designed for people like me finding faults on machinery, there are some that will do high freq's I had a B&K that was superb till I ran over it.
Your better using a 'scope and look at the current accross a load resistor, like the 0.1 ohm in the test jig I linked you to.
The test jig can also be expanded to get an idea of switching losses, however you need to get to that point first.
