Nice. As you noted, the bubble section needs some work. Anyone following this will miss a lot of pushes, especially from the SB.

For example, suppose it's folded to you in the SB on the bubble with a stack of a little over 1200 at 150/300 blinds. BB has about 1500. That's 2 points for SB + 2 points for bigger stack behind + 4 points for stack size. So you have a total of 8 and push 55-44, any ace, KT/K9s, QT/Q9s, JTs. In reality, you probably need to push any two there.

Position is more of a multiplicative effect than an additive one. I haven't thought this through completely, but what about something like multiplying stack size in BB times 0 for SB, 1 for button, 2 for UTG, then add your other factors?
