What level should I be competing at?
Here is an extract from the rules, that explains what level you should be competing at.
The following are the WMAC guidelines that allow athletes to determine which grade level they should be competing in. These are as follows:
Bear in mind, these are guidelines. If your style uses different time frames, please use those as your guide for the fairest possible outcome.
If you have changed styles, and used to be a higher grade, please ensure that you compete at that higher level where appropriate.
Every style of martial art has a different grading system, with different belt or sash colours, if any at all.
It is very difficult to determine equivalencies with someone from another style e.g. 4th Kyu or a green belt, if they don't use the same terminology or colour scheme as you do.
Even if they do use the same numbers - do they use same scale? How many levels to black belt? 10? 8? 6? Is black belt even how you distinguish your first major level?
This scale here is meant to help you decide what level you should be selecting when entering WMAC events. Bear in mind though that training times for children might well be longer for the same level than for adults, and this should also be taken into account.
If you have changed styles and started as a beginner again, say, from karate to kung fu, but had a black belt in karate, you should be sparring in the Black Belt divisions, but for forms, you could be competing at beginner level, since they would be completely different from the karate forms.
If an athlete is exceptionally good, regardless of grade, consider going to the next level rather than languishing in the “correct” level. Is it about winning or challenging yourself?
