You think it’s not a good way of looking at it?
Hmmmm....how much does it differ from number of retirements?
The ones that voluntarily retire tend to have a lot of experience. There are exceptions though.
That's what I think alright. You can't combine peoples experience, it never works that way. If it did, you could assign calculus problems to a first-grade class as a group project and get the same result that you would from a college math professor.
