Thanks for information, Galina !

It was really helpfull for me.

Yes, I meant exactly that. I see dashes in "%" columns for most of the tests.
Sorry for my wording inaccuracy that caused this confusion :(

Right, I did't know I should. Now I see how it works.

So, great to see that such a new tool is already able to reveal interesting results. Thanks !
