Resurrection of a dead thread. I have the solution for you as I was trying to solve the same problem.

One user posted a link to how to brew. This is actually correct but you have to manipulate the infusion formula and solve for Tw.

Wa = your sparge water volume in quarts
Wm = total strike water - volume of wort collected in quarts

I made myself a calculator to use with excel. I’d be happy to share if anyone is interested.

You also need to account for the thermal mass of your mash tum.

I find that Beersmith accounts for the thermal mass as well and is very accurate as long as you have your equipment and parameters entered in properly at least in my limited brewing experience.
