Like I said, same system gets me 83% when I fly sparge for an hour.

What's your conversion efficiency? It sounds like you aren't finished at the end of the mash rest, and the long sparge is giving you extra time to get full conversion.

Not sure what conversion efficiency is but I mash for 60-90minutes, depending on the beer and always raise my mash to 168 by adding boiling water to stop conversion/allow for better sugar extraction. For batch sparging I drain and then add my sparge water and drain again. I do this as fast as possible but like I said my outlet tube is small. Maybe it's not draining fast enough. I don't mind. I just set my efficiency on Hopville to 70% when I know I'm going to batch sparge and I get good results.

If I'm not mistaken, I was sitting just to the right of Sean in that picture.  He was doing a fair job of killing brain cells at the time.

I think that one is from Club Night, but from a brain-cell-killing standpoint, the entire weekend was pretty ambitious. I was a little worried, but I look at Denny and... Wait, what was I talking about?
Beer is like porn. You can buy it, but it's more fun to make your own.

In batch sparging, the speed of runoff makes no difference to your efficiency.  Do you stir in the sparge water really well?
