Default To mash out or NOT to mash out

I'd just like to hear from other experienced brewers. Do you mash out? Is it really necessary? Please give additional info to support your position. Thanks very much!!

For fly sparging it's pretty much a necessity IMO. For batch sparging it's totally optional, and IMO the water could be better used to increase sparge volume.

I get slightly better efficiency with a mash out. If I'm lazy I just start heating the runnings up the minute the kettle bottom is covered, which should help stop or slow enzyme activity.

I always mash out. I am a fly-sparger and it helps the mash run more smoothly.

I always mash out when fly sparging, and it increased my efficiency by 10% (from 75% to 85%)
I never mash out when batch sparging (which I only do if I am in a hurry). But I do heat the mash water hot enough to get the grain bed up into the upper 160's when batch sparging.

I batch sparge and don't do one unless I'm decocting a German lager. It dosen't increase my efficiency. It can if you don't have complete conversion.

I mash out. At the very least the temp increase helps thin out the sugars in the wort so it can flow easier.

I don't worry about it, and put the water into additional batch sparge volumes. Too much work for me. Kyle

I mash out as that wort has to be heated to boiling anyway. The BIAB grain becomes much more fluid, which I think makes the dunk sparge easier to extract remaining sugars.

I batch sparge. Tried with and without and didn't see the point of doing it. The first sparge addition is normally hot enough to raise the temp of the grain bed.
