Big beer efficiency and fermentation question

He batch sparges, which is why I was confused on how a longer time spent sparging would increase efficiency.
At any rate, the main factors for increasing my efficiency (even on 1.070+ beers) was a tighter crush (thanks Denny!) and a thinner mash. I mash nearly everything at 2 qts/lb if my 10 gallon mash tun can hold it.

Another strategy you might want to consider is to simply alter your efficiency targets for your big beers rather than chasing a bunch of possible tweaks/fixes. As long as you're consistent, even it is lower, you'll be able to calculate and hit your volume/gravity targets just fine.

With either method, it would increase efficiency if conversion isn't complete at the end of the mash rest.

I find conversion is done in 15-20 minutes, and certainly within an hour. Mash time is not a factor in my experience. YMMV?

True. I was making a quick assumption that conversion was complete after 60 minutes.
