Anyone have a gap setting you use for BIAB?

I use a gap of 0.030", and I run everything through the mill twice. I get a consistent mash efficiency of 81%. I have heard of BIAB people who go even lower on the gap, but I don't see any reason to do so.

Perfect! Thanks. I'm currently set to 0.038 and knew that was too wide for BIAB but I didn't want to just start adjusting blindly.

I read something awhile back that said you can use an old gift card as a rough gauge on the gap needed. I use a Schmidling Malt mill and always seem to get low to mid 80's with that setup. Just my $.02

After reading this thread last week, set my mill to 0.30, double crushed like usual and hit 80% mash efficiency for the first time with BIAB!  Thanks for the tips!
