Thank you for your answer.
I have tried with the completed task perspective you describe but it is insufficient for my purposes. Maybe if I could export the perspective with tasks and associated metadata to Excel I could do the analytics myself, but I’m not aware of this functionality either in OF. ¿Do you know if it can be done?
I understand you would need to access the archive to be able to develop this back time functionality. I guess it is not easy but not impossible either. Else, at least the new perspective could show what is not yet archived and I would need to run and export this perspective periodically before tasks get archived.
I don’t really care about time tracking in this functionality, in more detail than a day. I don’t use time estimates for the tasks and do not measure my productivity. What I would like to be able to analyze is if my time allocation matches my values and priorities and other ad hoc tags I can add to the tasks in a general view.
I have used toggl a couple of times when I did want to measure how I spend my time more in detail. I agree Toggl is a valid tool for this analysis, I just wanted not to have to log twice the same task in both systems and instead use the timestamps and metadata existing in omnifocus for each task. But as you suggest, maybe an integration interface with toggle or a similar sw would be an alternative.
Maybe another alternative could be to dump the OF Archive to Excel and do the analytics in Excel.
So I guess, to summarize, I would like to see the time back perspective in OF and be able to download it to Excel. Next, I could work with the raw export of tasks and associated metadata from OF if it could be done in a consistent way, and , third, I could dump the OF data into Toggl or similar to take advantage of Toggl functionalities.
I am not aware that any of these alternatives are possible today
