looks like to me that he removed the 1st runnings, then added more water. More of a batch sparge than a pour over...

I saw that he removed 4 gallons of first runnings, but he mashed with 10 gallons, meaning he left a lot behind while doing a sparge. I'm still not getting what actually happened.

Sorry - was out of town last several days.

You have it right - I mashed with 10 gallons.

After the mash I suspended the back from a ratchet pulley overhead and drained out approx 4 gallons, leaving approx 4.5 gallons in the keggle.

I poured 4.3 gallons through the grain bag, gave it a good squeeze and added back the 4 gallons for first running.

All of that gave me just under 13 gallons pre-boil.

Make sense? If not I can post some pictures next time I brew. It worked out well and I hit all of my numbers right on, so am definitely planning on using this method again.

Oh totally makes sense now. You just did a typical sparge, but removed a few gallons beforehand. Any reason you pulled those 4 gallons out before sparging?

I had to pull out the 4 gallons to make room in the keggle for the pour over, keeping in mind the grain bag was still hanging partially inside the keggle.

Once I did the pourover and pulled the grain bag completely out, there was room to add the 4 gallons back in.

I'll post some pictures of the whole process next time I do a 10 gallon batch in a few weeks.
 
Okay, yeah, that sounds pretty typical sparge then. In your first description when you said you sparged then pulled the bag I thought you were just adding more ground water to the mash with the bag and grains still in it.
