I am interested how to adjust beersmith for the boiling down of the first runnings, any ideas?
I know what you mean. I don't use beersmith, but I just work around it in my software (beer alchemy). I built my recipe around a 7 gallon boil, initially. I can't input a caramelization in the software so I know that I need to either run-off almost 9 gals of wort or add top off water to make up for the loss of nearly 2 gallons. In short, setting your boil volume and total runnings to 7gals is the best way to go.
