Thank you for the answer.
Years and education are easy and fine. The criteria for hours is more challenging as we do not have to track time spent. Tracking time spent on projects is something I started only recently (last year). Calculation of hours for past projects in my case will and can only be an estimate based on "raw" data such as emails, reports, and calendar entries. It's, by the way, a lengthy process which, I hope, is acceptable.
Best,
