Custom Fields - how many?

A Simple question - how many custom fields are there in OCD 6?
It seems there are ten text fields, ten checkboxes, 5 date fields and something else - I don't remeber exactly for album and track pages in total. But the dax editor shows tags like

albumcheckbox1
albumcheckbox2
......
albumcheckbox9
albumcheckbox10

AND

trackcheckbox1
trackcheckbox2
......
trackcheckbox9
trackcheckbox10

So - how many of them? 10 checkboxes for album and another 10 checkboxes for track, or 10 checkboxes in total?

There are 10 text fields, 10 checkboxes, 5 memo fields, and 5 date fields.

You should not make difference between album and track field with the same name, because if you, for example, put some value in "text1" field, "tracktext1" will automatically get the same value. It is the same field, it is shared by tracks and the album.
