grandfather sparge water volumes short

[1Floydbrew]

I have been brewing using the grainfather corrected version of Beersmith2 for recipe creation and it always seems that I am about a half gallon short of my 6.08 gallons preboil. I am wondering what parameter to change in the equipment setup profile to make this come up with the correct amount of sparge water? I could always adjust the preboil volume to 6.58 and hope that works . Any input would be appreciated. TIA,,,,, Floyd

P.S. Title should read Grainfather

Anyone?

Maybe your grain absorption % is higher causing your mash to be short, or you could just add 1/2 gallon more water to sparge with

I know this was a while ago, but I've been using My grain father for a while and BeerSmith2. I ignore the beersmith2 calculations and use the Grainfather formula in the app. always works well for me.
