to anyone who cares,

a one handed swing DOES NOT have a smaller radius than a two handed swing.

my "proof" (or rather - jack's proof) is no "thought experiment". it is a concrete proof. an undeniable proof. a clearly visible proof. AND a proof demonstrated by the very person who refutes it.

let's examine.

quote: "For the record, once I 'launch my hands' (knob to the ball), which to me is the beginning of the swing itself,..." by own admition - swing starts with knob to the ball.

let's compare clips: the FULL clip showing the batter's one handed swing and the SHORTENED version showing "launch sequence" only. reference the KNOB of the bat to the batter's anatomy when it FIRST STARTS to the ball. first, examine the clip showing the full swing. please,put your mouse pointer on the knob of the bat when it first starts forward to the ball. reference it to the batter's anatomy. what my eyes tell me is that the knob FIRST starts FORWARD somewhere back at the shoulder (certainly behind the batter's ear). now look at the SHORTENED "launch sequence" clip. clearly, this clip starts with the knob in front of the batter's ear (almost to his nose). much of the swing has been left out.
now examine when the knob first starts forward in the two handed swing. examine both clips (full swing vs. shortened "launch" swing). pretty damn close to the same spot.

continuing:

quote: ".....the reason I synched the two swings side by side."

i'm assuming that the camera was not moved, and that the camera angle is the same for both the two handed and one handed swings. it certainly appears to be.
please, with a simple ruler, on your computer monitor, measure the distance from the batter's left toe to the center line of the batting tee, for both two handed and one handed swings.
i believe that i am correct in assuming that the batter is FURTHER AWAY from the ball in the clip showing the one handed swing. further proof is the front foot in reference to the batter's box line. with this kept in mind, focus on the right hand of the batter in the few frames just before contact. reference the right hand to the background. use the pole forming the back left corner (as your viewing) of the batting cage.
in the clip showing the two handed swing the right hand does not go beyond the reference point of the pole. not so in the one handed clip. the right hand clearly goes beyond the pole reference point.

continuing:

look at the right elbow in both clips. look at the very FIRST FRAME of the "launch sequence" clips. which elbow is further away from the body?
it's clearly evident to me that the one handed swing elbow is not in the "slot". clearly, further away from the batter's body.

conclusion:

while standing farther away from the ball, starting the knob further back, extending the elbow farther away from the body, and extending the hands farther away from the body - i, we, all, (except the batter) can conclude that the swing radius one handed is LARGER than two handed.

more to come!
