yes you can, but you shouldnt and that was my point with the gun. you can pit them together but the resulting data gained is non consequential. its a bogus result. the gun will kill the bjj guy every single time, does that mean that bjj is useless BS? tests like that do not mean anything because while aikido and bjj seem similar they are non compatible concepts like bjj and a gun. nor can you qualify the successfullness of running away against bjj. these are all different contexts within a violent encounter. each tool has its purpose. again you can judge a screwdriver by how well its hammers a nail but what good is that? by putting Bjj and Aikido on the mat the only thing you are testing is ones ability to dominate and control.
and this is not really true in this instance. bjj will win every time, aikido will lose every time almost without exception. the usual explanation of "well its not a real fight...but if it was, my art would win......" that is a cop out. when people say that its because they do not really understand why aikido is not working for them. they do not understand the underling factors at work.
i kinda see aikido as an exception to most arts. it has by design no dominance and control game. thus it will always lose to an art that specializes in that. what Roy Dean seems to be suggesting is that it should adapt to have it. i say it shouldnt. it should be used as a different kind of tool.
