Yeah, there's not enough information provided to interpret that chart out of context for no-sparge. You need to have batch size, evaporation rate and boil time, absorption rate, and deadloss. For a no-sparge 5.5 gal batch of 1.070, 60 min boil, .75 gal/hr evap, .15 gal/lb absorb, and .125 gal deadloss, you'll get 74% mash efficiency, assuming good conversion.

I mean at 30 pounds of malt in a 5.5 gallon batch, youd be absorbing A LOT of your total mash wort, right? What if you doubled that water volume? What number would you have then?

Also, these graphs are cool, what is the "assumed" conversion eff. in these graphs?
I had done another worksheet at 10 gal. Efficiency goes up as the pre-boil gravity goes down and less points are lost, as expected. All these graphs were done at 37 p/p-g at 100% conversion - i.e. a congress mash. It's been a while since I read Kai's sparging paper but I suspect that's the small difference between his graphs and mine.
