Let me describe the highest level irimi Nage that Saotome can do. He had a Karate master punch him in the face as fast and hard as he could. He was able to draw the attacker off his feet With a gentle brush of his arm so he was literally horizontal feet first. Then he did an elbow strike before gravity took Uke down. I saw this along with at least 50 other people. This was not fake. This is Aikido at the highest level. This is not Diato-ryu.
What you describe here has the resulting appearance of what a close friend of mine, who is Aiki-jujitsu in a lineage associated with the parties here, accomplishes. The punch to the face curves, the soft bush continues the curve, bringing uke to a point of destabilization, the individual's center outside of their body....to be finished with a easy drop on nage part....maybe covered by an elbow strike. All this takes secondary pressure, push from behind, soft grip, transfer of momentum, weight drop, up and down spirals, use of the lower body, no tension in the upper body, proper rotation from the center (not hips first) and such....much of what is not clearly visible.....all of these things are not exclusive to Saotome Sensei or to the kind of Aikido you are trying to reach.
