I thought that I had touched on everything in your note, but then on further review, I realized I overlooked an important question you asked.
Yes, there is a correllation between your jo swing and the typical bo swing I practice. There are several interrelated components to the swing. Some of them include the folowing (in no particular order): grip, elbow position, hip position, sequential delivery, leverage, tip velocity, extension, control,
relationship/connection to center of body, fulcrum action, bo density, biomechanics, leg action, foot action, mid-section (consisting of tanden, l+r gamuka, an koshi), etc. A "sweet" bo cut, like that of a golf swing, is one where all the above (and more that I missed or don't know about) are in place. An
efficient, effective bo cut (and maybe some day I will develop one) should cut cleanly through an intended target. However, just being able to cut through the target is not sufficient if you can't recover and redirect the energy in the bo if you miss or after you've made contact. The ability to control the bo by correct and timely "squeezing" is essential.
I believe that the manner in which the above are put together for the bo swing is very transferable to the jo, both for offensive and for defensive reasons. Please keep in mind that I have not studied with a qualified jo instructor; however, the jo is used in early bojutsu training to work on developing some of the sensitivity and control.
