Brad and other advanced users, please check my results to make sure I didn't overlook something.
One lb of sugar as 1 gallon of wort should yield an OG of 1.046. This 1:1 ratio locks in a total number of gravity points for any volume. Thus, a 1:0.5 ratio should yield 1.092, while a 1:2 ratio should yield 1.023. Aside from preboil predictions, which I noted in another post, this matches BeerSmith's predictions with no boil off, trub or top up water.
The following recipe maintains a 1:1 ratio, but places 10% of the wort into trub loss (50 gal trub + 450 yield = 500 ttl). The result is a yield of 1.051, which exceeds the capability of straight sugar. This 11% rise seems steeper than straight linear. Doubling trub loss results in an even higher gravity than expected.
