A karate guy doing a kuzushi waza, known to us Tomiki guys as gedan ate. From what I have seen, this is very similar to how many competitive players throw this technique. He does it from a lunge. While this seems effective for the fellow, I believe this is not the most efficient way to execute this concept.
Now here is a version from Aiki guys. You will see the difference. They do their entering motion while the opponent is in motion towards them. This means it requires less motion on the aiki guys part to get in position to execute the technique. This is critical!!!
I truly believe this is one of the secrets to many of the techniques in the Tomiki system. If your opponent is in motion, a throw is easy. I think moving large distances to overcome an opponent is not consistent with "maximum efficiency with minimum effort" ideal of our style.
