I wanted to enter a few tournaments this summer. More than likely the 4.0 singles division. (They do have 3.5 and a 4.0 division for adults). I was confused at how they do the whole ranking thing and stuff. So my questions are: 1. Do I have to register to be a 3.5 or a 4.0 online? Or can I just enter the tournament in whatever division I want? 2. I was worried that if I sign up for the 4.0, that i'm locked into that division forever. Can I play down? Lets say I get romped in the 4.0 division in my first tournament, can I enter into a 3.5 tournament the next month? 3. How about the other way around, can I sign up for a 3.5 tournament first, and then play a level up and enter a 4.0 tournament the next month? 4. What if I sign up for an NTRP 4.0 singles event….can I sign up in a 3.5 doubles event with a partner? My partner is not as good as I(and I’m probably not that good, I haven’t hit since August). Thanks for anyone who can help!
