Not exactly true. It's just a couple percent change for the sparge portion, so it's a 1%ish change overall. Not a zero impact, but pretty small overall.
Actually, the real reason I and others have seen an efficiency increase by using hotter sparge water is because it ensures more complete gelatinization and conversion of starch IMO.

I did read a post where they add 1-2 gallons of higher temp (180deg-190deg) water and mix well before they do their first running. Also on the same post they had a link to what seems to be an very good page on no-sparge and batch sparge, and a well made calculator. http://home.roadrunner.com/~brewbeer.../nbsparge.html
(Hope posting that link doesn't violate any rules)
I helped Ken when he was developing that data and used to feed him my brewing data to verify his calculations. The info is good, but we've learned a lot since then. Take a look at www.dennybrew.com

With all due respect (and I have a ton for you), conversion can be measured prior to lautering, so those can be separated variables. If you aren't getting 100% conversion, a mash out into the 160s will certainly help you get there, but if you are already at 100%, then there is nothing left to convert.

OP I may have missed this but with the DIY mash tun are you using the SS braid attached to a single barb on one end? If so how long is the braid? I found using a longer braid (around 48") attached to two barbs on a tee helped prevent the braid from getting stuck up in the grist and improved efficiency for batch sparging. If that's a non-issue I'll defer to the other discussion points going on here but I hadn't seen any posts about equipment on the thread.

I completely agree. Maybe I missed it....did the OP say he was getting 100% conversion efficiency?

In batch sparging a longer braid shouldn't make any difference in efficiency. If it does, then you have some other issue that's the real cause of your problem.

Yes it is the SS braid with single barb, my braid is 24 in with a coiled SS wire inside to hold its form and keep from collapsing.

I don't see any problem with that setup.
