A question on the Brewers' Friend Calculator

Does anyone know, for when using the calculator, for extract brewing, at what time the calculator assumes you add the malt (liquid malt extract in my case)? I.e. does it assume late addition or full 60 min. boil? I am asking because I want to get to as close to the predicted IBU level of my beer as possible for my boil size. As I understand, AA extraction can be affected (reduced?) by the sugars in the wort.

Thanks.

In the fermentables section, if you "Add Custom" you can indicate that a fermentable (extract) addition is a "Late Addition", but it does not seem to specify exactly when/how late that addition is; I imagine it means "near flameout". As such, it looks like it will account for bitterness changes.

You should probably inquire with the Brewers Friend authors/operators, honestly.
