Greetings Mark Kruger !
I suspect I know what you think about your practice as well
Seriously, I can't give you any real opinion, because I have never done what you are doing. Sounds like you are really really good at pistol shooting, and you are in really good shape (ok, so I knew that already...) I know the tiny amount of cross training I have done has certainly informed my aikido. (So has accomplishing totally unrelated goals and having a daily meditation practice) However, I wouldn't expect training a bit in many arts to get me to the same level in aikido as would sustained, committed, daily practice in aikido. It might get me somewhere else well worth going, were that my path.
love to all at home - off to class.
