The worth in points means relative to the pot in that game, in terms of supply centers owned.

So we all paid 5 points to enter (thus people starting with 100 have 95 left), and the "worth" is calculated based on our relative power in the game. The sum will always be 35+/-1 for rounding. Currently Russia has 6 points because they have 4 SCs while everyone else has 3. Once we conquer all neutral SCs, the worth will pretty much be equal to SC count.

Now that you understand it, you can safely ignore it since those actual values mean nothing for a game like this (a winner-takes-all, and everyone shares equally in a draw).
