Another idea is to do a BOB and WOW test. This is something we always trained new engineers on. BOB is "best of the best" and WOW is "worst of the worst". It gives you a quick way to sort stuff out.

In this case you'll be guess which is the BOB and which is the WOW but even the guess can be informative. If what you think is the BOB turns out to make the same power as the WOW then that tells you something.
