Unfortunately not very good, which seems to be a trend. Sine wave is an up and down movement that was added into ITF patterns somewhere in the late 70s, early 80s to make it different from the Karate katas. It telegraphs the techniques and serves no no purpose other than to be different from Karate katas. It is not used in mitts practice or sparring. So this is a branch that does it the old way, but not very good. There is no hip twist to the punches and the overall form is mediocre.
