East Winds
2nd Black Belt
In competition, you are of course performing to a prescribed set of rules and of course you will be judged on how closely your performance adheres to these rules. This is exactly why 48 and 88 step taiji routines were introduced. (To standardise competition routines). These forms will also be in a different category to the traditional Chen, Wu or Yang routines. Adding your own postures to a routine will lose you marks. (No matter how good or martially effective these postures may be). So strickly speaking, adding modern Wushu techniques to a traditional form would be disastrous in terms of marks in a competition.
