By the title of the thread, yes it does. If you claim to do something you must prove you do it, and to what degree you do it. To aikidofy it, Aikido claims to be a martial art and one for fighting, so thus needs to prove it can do it and to a accetpable degree. (disclaimer i use martial art to mean for fighting, not the spirtual etc things that go with it)
Also he seems to sit inbetween two points, as far as i can tell. The first is, technique and style doesnt matter, as if you train realstically and for results the stuff that doesnt work will filter itself out. (if you let) the other is that flipped around. (no i didnt think it through and forgot the best way to word his other point)
His opinion of aikido is dervied from as far as he can see its training is ineffective so means if anything works in it doesnt matter. (and you cant pull a appeal to authorty on him if his credtials are correct, he is a authroty on aikido) I think in the block of "aikdio working" there are only a handful of techniques that are usually applied when people "get it to work".
Compeltely unrelated to the base point, but you should applied the engineering design principles here, you set a series of criteria then start building something on it. Then you assess something on the crtieria it is given, this shows up for weapons and vehciles a lot for the military. A tank isnt bad if it meets all the crtieria given to it, but the crtieria could be bad and not reflective of what is needed. this is just some general best way to look at things advise. (that does not mean you slap a 105mm cannon on a APC and call it a "MBT")
Addendum: When i think of the second point i have identified and how to articulate it i will post a seperate post on it.
Addendum 2: Rokas is also pretty open and honest about everything he does and eleborates his thougt process so you cant knock it there.
Addendum 3: I had a brain fart and mis read some things, the points made hold true but seem rambly because of it.
