In columnview mode the estimate is calculated[1] but the dynamic block doesn’t get updated.
I did some bisecting and the last version where both column view and dynamic block were working is: Merge branch 'maint' 1aeb958e5 Marco Wahl <marcowahls...@gmail.com> 12.02.2017, 09:19 In Use Org duration library 7e8cf5f4c Nicolas Goaziou <m...@nicolasgoaziou.fr> 13.02.2017, 14:41 neither column view nor dynamic block is working. For the column view this was fixed in: Merge branch 'maint' 2f200f50d Bastien <b...@gnu.org> 03.05.2021, 15:59 (But I don’t understand how this fixes the problem.) For the dynamic block the updating does not work. Since this was broken for 4 years I think no-one uses it. [1] The „est+“ function only adds integers and doesn’t work with times like 0:15. This is to be expected since it is a „+“ function, otherwise it would be „est:“. One could argue that an „est:“ function would be more appropriate, but since no-one seems to use this feature, I’m not the one to argue that. Maybe a note in the documentation would be sufficient: Note that this is a =+= function that adds numbers, not a =:= which handles times. Do you want a patch for that? Greetings Axel
