Wow, this issue comes very close to something I struggled for hours with
(3h42') last year.

It finally boiled down to this: sorting by effort in the agenda view only
works (correctly) when org-agenda-remove-tags is t. Here's the (edited) ECM
I created for IRC and eventually the list: http://paste.lisp.org/+7723

Is that still expected behaviour? Lack of documentation? The updated
org-agenda-compare-effort Nicolas provided doesn't solve this, at least.

Thanks
Yan
