Rob, > Is this a good way to determine the purity?
It's a good way to determine a baseline for your 50# bag. For all practical intents and purposes, that's what you want. See http://journeytoforever.org/biodiesel_make2.html#stockmeth and See http://journeytoforever.org/biodiesel_make2.html#poor before you begin for some ideas that could help you zero things in a bit.
