Thank you, I've changed to #+PROPERTY: Effort_ALL 2d 1w 2w 3w 4w 2m #+COLUMNS: %40ITEM(Task) %17Effort(Estimated Effort){:} %CLOCKSUM but there is no mapping between days, weeks, months and hours. For example, '2d' + '1w' is summed as '3:00'. How can I change this? The best for me would be to have the summed effort in weeks.
