I find this particularly interesting because I run a golf handicap site with a free account that lets you enter up to 5 rounds worth of scores. At that point, the demo shuts down and you need to upgrade to lift the barrier. The limit of 5 was chosen because it's the bare minimum needed to build a handicap (an inaccurate one, but nonetheless). But it turns out, as I've noticed over the course of the last two summers, most people upgrade when they hit the 5 round limit and then go bananas with it. I have one user who just passed the 150 round mark and most upgraded accounts have 35+ rounds. On the other hand, a lot of the accounts that I term "dead" are demos with one or two rounds in them entered in over the course of a few weeks. They eventually never come back to even finish the demo either: because they think my site sucks or it's just not something they're motivated to keep updated.
