batch sparging and efficiency

[BDogD]

3 runnings of 2 gal each should have a little higher gravity (i.e. a little higher efficiency).

If you carry out your batch sparges to the nth degree (n = the number of batch sparges) with n approaching infinity, it should become just like continuous sparging from an efficiency standpoint.

two runnings of 3 gal each result in a higher gravity than 3 runnings of 2 gal each?

Check out the 2nd page of the PDF that I posted earlier. There I show that this is true.
