I found a mistake. Near the end. It's a sign error.

X=(J-Z)-(J-Z-J)/M

This SHOULD simplify into

X=(J-Z)-(-Z)/M

So it's actually J-Z+Z/M

..Let's simply things even more.

E=JM-ZM+Z

That Z is the amount extra that Jerry is adding by not attacking, but instead just keeping it up for everyone else.

J-Z? That's Y!

E=YM+Z

This doesn't make sense. Adding Jerry's energy shouldn't make it take more energy to hold it up.

Either I've made a mistake, or there's something wrong with this model..
