- 1 for a solo.
- In a draw, (SCs you own)/(total SCs owned)
At a glance, this seems to have good properties, particularly compared to SoS.
- It is simple to calculate.
- Points totals don't become meaninglessly small for tiny powers, so surviving matters.
- It's completely neutral when centres switch between other powers; so there's no incentive either to cut down the draw or to keep small powers alive - you just want to do whatever is best for your chances of solo, or failing that your centre count.
[I know that there was a "Points per supply centre" system on the website at some point; but as I understand it this was a) not this and b) an abomination]
