Let's go dork.

Dear Dorkface, (I wonder what someone new to the forum would think?)
Yes, Of course- you need to prove any statement with additional statements if asked or show sources that can validate your proposition. During that process you either find out you're an idiot (hey- been there done that!) or find out that at least for now you are right!
I'm just saying that from a geometrical perspective- if you have one stick that represents the shoulder line (the clavicles move independently but we are just keeping them in-line for our example to prove the point at hand) and another stick that is 90 degrees to it i.e. perpendicular (obviously that's no exactly true either but again we are just isolating the essential issue here). Now, nail the shoulder stick to a wall- nail goes through the middle/half down the stick- i.e. at the neck/head if you are relating it to a golfer- with each end of the stick representing the shoulders. This stick is going to be able to spin around on the nail - like a spinning wheel- one end of the stick represents Matthew's "lead" shoulder - "orbiting". Here are the two scenario's:
1) If the second stick- representing the arm/club is perpendicular to the shoulder line stick- and attached at the end of the shoulder line stick where Matthew's lead/left shoulder is - then where is low point? It is opposite the end of the stick representing Matthew's left shoulder WHEN the shoulder stick is parallel to the ground. So this looks like a T except the vertical line is moved to the right side of the top line.
2) Now, when you change the vertical stick from perpendicular to the top line/shoulder line stick and make it at an angle to the top line stick 7 then low point isn't necessarily occuring when the shoulder line stick becomes parallel to the ground. You can move beyond parallel to the ground- have the left shoulder side of the stick continue to move "up" and the lower end of the vertical stick can still be moving down.
A few of the basic variables are how long is the shoulder line stick, and how long is the arm/club stick that is angled, and how much of an angle is the arm/club stick in relation to the shoulder line stick.
Bring back the questions - if your gravy brain doesn't understand what I'm saying or I'm an idiot. But before I go- here is what experiment I perform - that I would recommend that you perform to see what I'm talking about. Just take two pencils - and go through the above two examples and watch where low point occurs for the pencil that is angled in relation to the - "spinning wheel" pencil.
Better yet- just take your scissors and cut out a number 7- now hold the seven down with your pencil lead in the middle of the top line and when you rotate it- see if the bottom of the 7 - goes lower- down further - even when the "left shoulder" is moving "up" past the point of the top line being parallel to the ground. In either the 7 or the perpendicular one- low point ends up opposite the left shoulder.

I told you exactly what would happen- the boy hasn't even cut out his 7 yet!
When you get there and get the 7 cut out- have him poke his lead (please Bucket- don't!)- through the 7 and then have that 7 circle around on an inclined plane- then he'll have his top of the 7 moving "up & rear" i.e. on an inclined plane. Have him report back after he's done that and let's see what he thinks. If he doesn't have his 7 cut out in the next 2 weeks- I'll be driving to Ohio- you wouldn't like that UPP
