I've just found out that on the base circle, I can be perfect in one spot, and bump it, be perfect, hit it again, and be a couple loose. I've found this on about every grind from every company to be true. I always set tight at the loosest area of the bottom. I set my valves rather tight anyway, but that's just me. Try it and see if you get the same results. Now you have me curious.
