Well, Moriteru Ueshiba stated outright in "Best Aikido" that "styles that practiced compeition" (ie Shodokan) were not Aikido.

Of course, people have to make up their own minds as to whether they agree with that viewpoint or not.

I know that the "many roads up the same mountain" view is politically correct, but in all fairness, since some things are obviously not Aikido there must be some point at which something becomes "not Aikido", even in spite of some past connection to Morihei Ueshiba. The exact location of that point I leave as an exercise to the reader .

Best,

Chris
