I would ask your coach. I've actually never seen the rules online anywhere. Rules can vary by state - some use Level 9 rules (there may be some modifications) and some use the NHSF (National High School Federation) rules which are approximately equivalent to Level 9 in terms of difficulty. Your info says you're in Wisconsin which uses the NHSF rules.
Rules are not changing this year so the rules you found online are probably accurate. There are a few updates from last year, a link to them is in the middle of this page:
Welcome to the Minnesota State High School League The biggest change is a yurchenko vault can flip and twist in the postflight.
I judge NHSF so if you have any specific questions, let me know.
