Too generalized a question. When you talk about small committed, correct attacks, are you referring to in-close striking and grappling? Waza is simply the end point of a number of processes. My invitation to you was sincere and I think that you can easily understand how to enter, without colliding in order to execute techniques after spending a weekend playing with Ushiro Sensei. I look at waza as kata. Proper practice which emphasizes the development of underlying principles enables a person to be able to become increasingly capable of managing ones' self amidst conflict. When you get too caught up in trying to make your waza work, you are already behind.
