I don't personally use the clocking information like that. I just make 3 columns - one for the quoted time (estimated effort) I sent to the customer, one for the estimated effort which may changed during work on the project and one for clocked time side by side. I also snapshot the estimate for the project before starting work with C-c C-x i. This gives me a local subtree table that looks something like this: #+BEGIN: columnview :hlines 1 :id local | Task | Quoted | Estimated | CLOCKSUM | |----------------------------------+--------+-----------+----------| | * PROJECT Some Project | | 0:40 | 1:40 | | ** Details (not a todo item) | | | | | *** More details | | | | | ** DONE Task to be done | | 0:10 | 0:27 | | ** DONE Review project materials | | 0:30 | 1:13 | | *** DONE Review document | | | 1:13 | It's pretty obvious to me when they don't match. The actual number of minutes they're off by isn't important to me since the effort estimate is normally a rough guess anyway and clocking is exact (to the minute). Doing a difference on these two columns doesn't really make sense to me. When comparing clocked time to estimates I'm more interested in - this task was overestimated alot - this task was underestimated alot -Bernt _______________________________________________ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.
