I just started using BeerSmith and I have already made my first recipe. However, there are some gravity values than I can't understand where they come from.

How can pre-boil gravity be higher than post-boil? :/ I'm afraid I set up something wrong, but everything seems ok.

◯ Add water to achieve boil volume of 5,00 L

◯ Estimated pre-boil gravity is 1,059 SG

--

◯ Estimated Post Boil Vol: 3,50 L and Est Post Boil Gravity: 1,044 SG

◯ Add water if needed to achieve final volume of 6,50 L

Is pre-boil gravity not taking into account the top-up water to the kettle? (in this case 1,5L to make a total of 5L).

Even though, I made the calculations and doesn't make sense:

C0 x V0 = Cf x Vf doesn't apply. [59 x 5 != 44 x 6,5] --> 295 != 286

Thanks for your time!
