It won't help you create an average. There's just no way to do it, save for actually collecting data and doing analysis.
I know enough about stats to know that stats can be tough, but what I am getting at, most flyers will bang up their first couple of planes in the first few months of flying alone. It probably would take about a couple of years before a pilot is not as likely to carsh their plane. I know that every plane can/ may crash and every pilot is different, but most beginner pilots will crash a couple of planes a few times in the first couple of years.
