I think my post below doesn't make something clear I do encourage everyone to do quality testing, as much of it as they can figure out (other than specific gravity or viscosity which I think are not useful tests, at least when performed on unwashed fuel) I just want to also make the point that quality testing of course helps you refine your process. as far as the German testkit we were talking about goes, just doing PH testing of your unwashed fuel will tell you about catalyst or soaps, and probably give you a good idea that you should wash the stuff. Acid number (titration with KOH, on washed fuel) will tell you about unreacted free fatty acids. Washing with vinegar or other acid in the wash water will throw off the ability of that test to tell you about your process.
