Ok, I now understand how to do equal batches. Here is how I have beersmith setup.
Batch Sparge using batches that fill 100%
Sparge using equal size batches
I'm adding a bit of sparge water before I collect the initial mash runnings and then all I have to do is sparge with the same amount of first runnings that was collected into the kettle plus .75 gallons, because of the dead space in my MLT. So, I'm only doing 2 seperate runnings, but they will now be equal.
