Totally agree. Whatever benefits may come from form practice, you don't get them just from memorizing the choreography. Whenever I see someone describing a test or a competition and they talk about making mistakes (or not) in the sequence, I think something is wrong with the situation. By the time you've explored a form deeply enough to get any genuine use out of it, the choreography should long since be second nature.Not every system uses forms/kata/poomsae, and that is fine. They are not necessary in order to train a martial system. But if they are used, then they need to be trained diligently and they need to be explored to understand the lessons that they hold, and to drill that material. Otherwise the forms practice is useless.
