So, the last couple all-grain batches I’ve done have been batch sparge as opposed to fly sparge.  I only brought my sparge water to 170 degrees.  What I now realize I didn’t account for was the fact that the grain bed lost quite a bit of temperature during the first drain.  So, with this new information I heated my sparge water to 180 and when I added it to the grain bed ended up with a temp of 168 degrees.  So, this will be the new sparge temp that I aim for.  Also, with beersmith I tried the equal runnings options and hit the target pre-boil gravity exactly as expected.  Way cool
