I go for anywhere between 1.25 and 1.5 quarts/pound and anywhere in between. I try to end up with 5 gallons of sparge water to get two sparges at 2.5 gallons each (give or take a little).
Double batch sparges have given me an average of 85% with a high (twice) of 91%. This is with a stainless braid on a round 10 gallon cooler.
