My number per week also varies depending on time of year, activities of my children and my real job.
1) So far this season, 43 games worked (6 varsity) and 24 more scheduled (including rec ball - 2 more varsity).
2) Working about as many as I can given the above factors.
3) No, but are at the level I expected. I'm in my second year of officiating (first year in my chapter) so I have more varsity than I expected but not as many as I would like
4) I'll work any game given to my by the assignors. If the chapter assignor thinks I'm ready to work a game at a certian level/school, who am I to argue?
5) Keeping working hard and learning the job...bigger and better assignments are coming.
