the norm is about a gallon an hour for my 5 gallon batches...you want a vigorious boil to break down the hop oils...I was not getting this when I had a weak boil on my stovetop...
Most all grain batches have at least 2-4 extra gallons of wort to boil down after sparging... since my efficiency is around 85% with less I dont use as much sparge water as the recipes suggest but still end up with 1 1/2-2 gallons of extra water to boil down in a 5-5.5g batch.
I sometimes dial mine down to around 40/50% in manual mode and sometimes just set it to 212 and leave it.... it seems to work just as well either way.
