In my example I have page a and filter it out on hit level in a segment. Then I get 100% entry rate.
When looking the entries and visits it is the same amount and when doing a breakdown I see why I have the same amont of visits and entries because it includes all pages which had an entry during my visit on page a. So I still think this makes it too complicatde and not easy for users to work with. The same happens with Exit Rate and Bounce rate as well.
