True. although those are just variations on attack, but that's not necessarily discussing technique. Each technique, like nikyo itself, has several different directions of entry/turning and release/pin that could be considered different enough from each other to list separately.
True, but you are missing the fact that Nage's method and choice of application of a technique neccessarily depends on Uke's methhod of attack.
Either way, I don't count variations of a technique as individual, seperate techniques.
