Re: Data format for keeping track of weekly & yearly stats?

This looks like the promised land here. SQL aggregation in org-mode omg X-D!!

Pretty much what I was looking for. Thank you so much for the link.

Hi Leo

You may want to have a look at org-aggregate
It provides partial sums, means, and so on,
and also correlation between two columns.

Source code and documentation here:
  https://github.com/tbanel/orgaggregate

Also available as an Emacs package on Melpa:
  (require 'package)
  (add-to-list 'package-archives
    '("melpa" . "http://melpa.milkbox.net/packages")
    t)
  (package-initialize)
  M-x package-list-packages
  install orgtbl-aggregate
