Playing with BeerSmith's Hop Bitterness calculator I note that it's plugging the starting wort gravity instead of the average wort gravity into Tinseth's formula.
I found an old thread about this here: http://www.beersmith.com/forum/index.php?topic=13057.0
But the resolution is unclear and the link to a "more approriate thread" 404's for me now (http://www.beersmith.com/forum/index.php/topic,13062.0.html)
Tinseth's article pretty clearly says "average wort gravity" (https://www.realbeer.com/hops/research.html)
What's the reasoning behind BeerSmith's difference here?
