I didn’t get to the MD Ren Faire this year. (The day we had tickets for was the day they cancelled because of the rain storm, and when we tried to get tickets for a later weekend they were all sold out.) But I have been most years for the last 30 years. (My husband was an actor there in the mid 90s. He played Lord Cloverdale.)
The jousting at the Ren Faire (both the current group and the former group) is mostly a simulation of medieval jousting with two “knights” charging at each other with lances. The tips of the lances are designed to break off if they get a solid hit. They sometimes do a single run spearing relatively large rings along the sides of the arena.
But it is nothing like the “MD state sport” of ring jousting (which I have only seen once in person), in which each competitor makes multiple runs, with the rings getting smaller with each round.
There might be some crossover, but even if there is, I doubt that it would make a significant difference in the turnout for ring jousting. I just checked the MD Jousting web site (http://marylandjousting.com/ ) and they have plenty of tournaments during the run of the Ren Faire.
