    In the recipe editor, the hop total is wrong. I have a recipe that uses 93g of hops, but the total at the bottom says 96.39g.

    The IBU calculations also seem to be a little funky. It's a small batch (5L), but something weird going on.

    1g warrior at 40m = 0 ibu
    2g warrior at 40m = 21.5 ibu
    3g warrior at 40m = 21.5 ibu
    4g warrior at 40m = 21.5 ibu
    5g warrior at 40m = 43 ibu

    It used to be much more granular in that a 1g change would make a difference.

    I had a look at this and there seems to be something "out of the ordinary" about how the IBUs are calculated between a recipe and the IBU calculator.

    I created the same conditions in a recipe and in the IBU calculator - the areas shown highlighted in red in the screen shots below.
    An OG of 1.055, Boil Gravity of 1.043, a total of 5 grams of 20AA pellets boiled for 60 minutes. I split the calculator hops entries to see if there was any effect on separate lines of hops - it looks ok.
    The recipe shows an IBU of 14.64, The calculator shows an IBU of 12.89 (The areas shown highlighted in yellow).
    Why is there a difference? Is it me or the calculators?
