Thanks for org-collector.el, now I have read it and tried it out.

It is very nice to have the possibility to evaluate lisp expressions as
values, that is something missing in org-columns!

But it was only a few seconds faster than column-view and column dblock
and therefore not fast enough for my slow computer ;-). I timed it to 62
seconds to insert exercise data table for one year (83 headings) with 4
columns and no calculations.

It is clear from above who is the time thief.

* Comment

It did not work at first because sometimes I have properties without
values, they then gets the empty string assigned, "".

I had to adjust function org-read-prop because in my emacs (GNU Emacs
23.0.60.5):

(stringp "")           -> t

and

(string-to-number "")  -> 0
(string-to-number "0") -> 0

and then at line 34 it tries to take substring out of "".

Attaches diff if interested :-)
