I am basing my comment completely on Dan's description nothing more... and of course... we both could be wrong.
Now...90% of other Dojo's is also an interesting number and the survey you base this statistic on is....Where?
Gosh Sensei Fooks... You're not suggesting that Aikido is not technically sound as a Martial Art or a system of "Self Defense" are you?
My point was very simple. Dan hasn't talked at all as far as I can see about how Aikido is trained in his club. All he's said is that he hasn't found it useful for him. His dojo is also public record as it's part of his profile.
So what you've done is effectively publically called the Luton Aikido Club a mcdojo where the senior grades are diluting the art based on the fact one particular student, with no more than 2 years training hasn't been using it in bouncing work.
If it were me I would want more evidence before pointing a finger at a particular school and calling it McDojo....
