Shane makes some good points, ALL kata/forms training should include Bunkai/breakdown and then OYO/drilling the techniques. Kata is often seen a a sequence or a fight rather than a grouping of techniques to pick from. Whenyou are alone the help with footwork, transition, syncing the breathing with the movement, body postion of a techniques , angle of strike. then when you OYO or drill you refine the timing and intent with your partner. this way you do not think about Kata in a fight but rather react with what you have drilled
