What is the meaning of the number in the upper-right corner of the Watchtower screen?

The values also seem very suspect. All my logins have long, complex. and unique password and my rating is “fantastic,” which seems reasonable. But…I put the beta on my wife’s phone and she (despite me trying to help her) has passwords that are all weak, short, and frequently duplicates, and her rating is “Very Good.” - So now she thinks her password practices are fine, which clearly they aren’t. It seems to me that this is the exact opposite of what the people at 1PW would want to accomplish with this feature.
