I understand your point Yari, and sorry for not being more clear. I was thinking of the skills each man posses, are they developing higher skill than that of O'sensai.....and before I get hate posts let me explain my thought process on this:
You have an instructor who has been training for ten years when you start training with him. He is obviously more skilled than you by the fact he has had more years training. So you learn from him and before you know, you have tained ten years, but he hasn't stopped training, so the instructor now has trained for 20 years. Simply, the more you progress, he also progresses. Finally after he has trained for 50 years, the instructor dies (for whatever reason), you however continue to train. You have seen the skill of your instructor after 50 years, so that when you reach that same point, you continue to train but also refine your instructor teachings to a higher level than your instructor, because of witnessing the higher level, your level skill is higher than his when reaching the same point.
This is my train of thought, even though I may not have made much sense. Mainly, just to recap, do you think that the successer's of O'sensai's aikido are meating his same skill level, surpassing it, or would be a dissapointment in his eyes? (It's safe to say though that the latter of the question isn't an issue)
