I brewed today for the first time in 6 months. (Ugly story that I don't wanna extrapolate on right now.) When it came time to sparge, I considered batch sparging, but I didn't quite have the motivation to look up how to do it and think about what will change with my set up, so I pulled out my sparge arm and let'er spin. An hour later I put the pot on the stove and went out for sushi.
I'm gonna batch sparge my next batch in a couple of weeks to give it a try.
