You're right. I didn't express it very well, but my point was really about where you choose to cut people out of your premium offering. As it stands, you're doing it 'on the way in', as it were, i.e. while people are entering data. I was suggesting you do it 'on the way out', i.e. when people have taken the time and effort to build something for themselves using your app, and now want to do something with the timeline. That's separable from the question of how to actually make the cut-off (and deleting data, as you suggest, may be too brutal) But anyway, it's just thinking out loud rather than a definite suggestion.
