Hi Mikael,

I ran into a very similar issue with column view lately while trying to
use org-mode to collect experimental results.  I created the attached
file, which can be used to collect data from properties in a manner
similar to column view, but using a simpler method meant only for table
display, rather than column viewing, and allowing for the application of
general elisp to the values before they are dumped into the table.  I
think it would work in your case as well.

I applied it to the data you posted with the following results.  The
mechanics are working, but it could use some display cleaning.  The file
`org-collector.el' is attached
