This time I'm going to ask somebody else to test my model. So I'm going to ask my daughter, who's much smaller than me, and see if the estimated actions are as good. Let's try it now. Okay, so we're still getting some good movements here. A few bad, and we're not following the serve pattern, but a few mistaken good ones as well. So my model is working fairly well for a different person, but perhaps it could be refined a bit.
