Compatibility ratings missing on some profile pages

I was looking through my 'Similar members based on Movie ratings' area on this page and noticed when I went to the profile pages of some of these members, the Compatibility column said None for the following members:

korenagakai.listal.com/
griffth.listal.com/
tharens.listal.com/

Also, will there be some way in the future to see in this area which items you have in common with the other members? And compare your ratings with theirs like you can with lists? If you have 100 items in common with someone else that you both rated 1/10, that's not as helpful as finding someone that you both rated 100 items 10/10.

I've fixed the compatibility problem, added the last part as a suggestion: www.listal.com/suggestion/369

I have a quick question - when the compatibility message that comes up when viewing another user's choices (which I don't see anymore) says that items they've ranked high only appear if they're not in one of your lists, do they mean "one of your lists" as in your official Favorites list? Because I see some movies that are in some of my custom lists. Also, it just makes sense to discriminate only if you already have a movie added to one of your Favorites lists, since you could have a hidden gem that you added to one of your miscellaneous lists absentmindedly and still not have seen or appreciated.

I hope that all makes sense to you guys? =?

You should see it if you click the view links under recommended. By not on your lists it just means items not marked as watched or want to watch, I might change the text of this.

Out of curiosity,how is the Compatibility rating calculated?
For instance, what does "83% 4 items" mean?

sorry it's a while i'm not so active in the site, now i can't see the compatibility percentage in the other user profiles, where is gone?

yuhuuuu, anyone here?
