All I can add is don't get too cocky closing the gaps on your mills. I was thinking I was a fantastic brewer getting 85-90% then noticed my beers weren't as good. Astringent and clarity issues in every brew. Lots of flour and shredded husks. I opened the gap back a bit to where I get between 75-80% and all was good again. I think I have mine set at .035 now. Had it down to .020
