I'm at 72%.
I'm going to switch screens to a punched stainless false bottom next.

Anybody brew in a bag or all grain and have any suggestions on efficiency increase?
It's bad form to hijack somebodies thread, and you should start your own, but...
I question your 90 minute mash.
You don't need to mash for 90, and I never have adjusted my PH (Seattle good neutral water).
Usually it comes down to grain crush... it should be slightly coarser than cornmeal.
I was getting 80% pretty consistently.
Oh, and squeeze the bag... I was only loosing about 1 qt in 12 lbs of grain.
