No- what I meant is that if you put 4 gallons in the HLT, that's how much you'd have in there- so you wouldn't have to measure it going into the MLT, if that makes sense.

If you have gone so far as to put ball valves and brewmometers on your rig then I suggest getting a sight glass for your HLT at least. I get by without an additional one on my kettle. Accurate early measuring and math is accurate enough for me in terms of kettle voule.

You could start with 6.25 gallons, and have some extra wort aside to add near the end of the boil if you are boiling too much off. (Add it with at least 15 minutes left, though!)
Well, my plan is to shoot for 6.5 gallons (13 for 10 gallon batches) and then check the gravity and adjust the wort accordingly with water or LME.
I'm just trying to see how I can figure out what the gravity at 6.5 gallons should be if, for instance, I am shooting for 1.048 @ 5.5 gallons.

Simple math.

5.5 gallons x 48 = 264 points

264 / 6.5 = 40.6 or 1.041 ish

Or you can use Brewsmith sw which gives the estimated pre-boil gravity.

D'oh! I should have been able to figure that one out, lol!
Thanks!

I could do that too, since I got the Brewsmith cd rom for Christmas!
