I had 38 HS games....(half of them in "3-Person").....5 college games....6 post-season tournament assignments. That was about what I do year-to-year. (Been doing this for 34 years.)
Also do some "local" community AAU, club & traveling tourneys (10) when dates permit.
Got to be careful that you don't set yourself up for injury....especially the "older" you get!
peace!
