Exclusive segments help?

I’m sorry to ask, I promise I’ve searched here, YouTube, and I’m none the wiser!

Just got into the app (and I’m loving it!), figured most things out but trying to display my Apple Watch rings, I’m getting stuck with the exclusive segment part, and what I’m supposed to enter where to make the rings close.

I’m sorry if I’ve missed it, but is there somewhere that actually explains how these work so I can set my daily goals to make the rings complete? I’d love to actually understand what it’s doing so I can use it again for other widgets. I feel I’m missing something obvious!
