I've been conditioning the malt before crushing it and it works great. I crush it at .0032 and I can run the pump wide open the whole time stirring every 20 mins. or so. I get 84% efficency every time.

I have not stirred my mash during the rest. I guess I thought it better not to be disturbed. My crush is .032 as well. I have only stirred the grain during the dough in.
I am also considering changing the mash return tubing. Currently it sprays a fountain of sprinkling wort on top of the grain. Maybe it should be setting on top of the grain bed.

I recirc, push water thru coil to get wort out to bk. I then recirc hlt spare water coil to heat to 173 (to bring bed up to 168), add spare water. I then either just recirc thu pump (no coil) or if I recirc thru coil I'll use some extra water to get all wort to bk.

Gentlemen, I believe you have found my efficiency problem. I have simply been redirecting the mash circulation to go straight to the BK, by switching a valve near the pump. This cuts off the coil. Then during sparge the leftovers stuck in the coil was circulated briefly over the grain and drained to the BK. this still left the coil full of sugar.
I need to redesign the plumbing between the coil return, and the BK whirlpool return line.
Any ideas?
