I think you might be right
The following is from two interviews with Katsuyuki Kondo conducted in 1988 and 1992.
How do you view the relationship between Sokaku Takeda Sensei and Morihei Ueshiba Sensei?
Katsuyuki Kondo: This is just my personal opinion, but Morihei Sensei studied Daito-ryu for over twenty years and served Sokaku Takeda Sensei as his master. Sokaku Sensei looked after Morihei Sensei as his student in various ways. There are many stories about this aspect of their relationship, illustrating the courtesy of a student towards his master and the affection of a master towards his student. This relationship continued for a period of time, and at a certain point Morihei Sensei began to seek his own path and eventually created modern aikido. Morihei Sensei was a great person, and I believe that anybody who can be called great always exceeds his master. I do not know that Morihei Ueshiba Sensei exceeded his master, Sokaku Takeda Sensei, in terms of technical ability, but I think that realistically speaking, Morihei Sensei far exceeded Sokaku Sensei in terms of number of students and also the extent of his reputation.
Sensei, you mentioned the designations kyoju dairi and soke dairi. Historically, what do the kyoju dairi and menkyo kaiden qualifications mean and who has been awarded these certifications thus far?
Katsuyuki Kondo: There are quite a few people who received the kyoju dairi during Sokaku Takeda's time. Morihei Ueshiba Sensei was one of them. Also, there were Kotaro Yoshida Sensei, Kodo Horikawa Sensei, Toshimi Matsuda Sensei, Yukiyoshi Sagawa Sensei; all together I know of eighteen people who received the kyoju dairi from Sokaku Sensei.
From an interview with Kenji Tomiki.
It was in 1926 that Kenji Tomiki first met Morihei Ueshiba in Tokyo and was highly impressed by the latter's mastery of jujutsu techniques. After graduation from Waseda in 1927 with a degree in political science, Tomiki entered graduate school majoring in economics. During the summer of that year he spent a month of intensive training in Daito-ryu aikijujutsu under Ueshiba Sensei at the Omoto headquarters in Ayabe, near Kyoto. For Tomiki, Ueshiba Sensei's art included a huge body of essential jujutsu techniques which served as a vital complement to his judo training.
