It tells you something about the distribution of people upgrading.
You are correct that each everyone's case is different. So there is no "one size fits all" model here. But looking at the distribution you have an idea of how many senior folks are still getting on the upgrade train and by inference have an idea of when you are likely to hold a line etc....
