I do a double-batch sparge, so I add half of my heated water, do the thing, then add the rest and stir and sit a second time.
do you get better efficiency doing double?
time is not the issue with batch sparging... though I prefer to add my sparge water, stir, and wait 5-10 minutes before vorlaufing and draining.

I don't know about Silver but I absolutely get better efficiency doubling up. The only issue is when you do a big beer and the initial mash in gives you a large first running so your sparge volume is too small to split.

Is it OK to sparge with water @ 185 *F? I was under the impression that getting it above 170 *F was somehow detrimental. Or are you assuming the soaked grains will bring the sparge temp down?
Since I started mashing out with the absorbed volume (I bring it to a boil to get the grainbed temp up) and splitting my sparge into two separate sparges I have been getting 85-89% efficiency. I also drain the tun fairly slow, maybe 50% open on the valve, it makes for a clearer runoff too.
It depends on the temp of the grains, when I add my mashout water, say for an 11 lb grainbill I use just over 5 quarts of water, if I bring it to a boil and add it to a mashtun sitting at 154° it will bring the temp up to about 165-168°, after this addition I make all remaining sparge additions at 170°
OK, that answers my question. I work on a much smaller scale than that, so 185* sparge water seemed a little excessive.
As a sidenote, how do you get the degree symbol? I'm sick of using the asterisk.
