It would seem to me that if you're getting 70% efficiency on the system there are likely any number of things you could do to boost that. You don't say what your sparge methodology is either (batch/fly/no)??

It is 15 gallon stainless, flat bottom mash tun. There is 2 gallons of dead space under a flat stainless false bottom and the drain valve sits approx. 1 inch from the bottom of the vessel. I always recirculate and do a mash out at 168 and let that rest for 10 minutes.
I fly sparge, keeping approx. 1 inch of water onto of the grain. I run off approx. 1 qt per minute into the kettle to achieve an 8 gallon pre-boil volume and shoot for 6 gallons at the end of the boil.
My boil off rate is pretty high (approx. 25%) and I have always attributed that to the wide kettle. I'm no scientist, but it seems to be that the more surface area of wort in the kettle provides more area for evaporation.
So, do you guys a pick up tube on a flat bottom mash vessel is helping or hurting? Like anything else, just brewing will determine that, right!
