Wait a second.
If free spirits are able to get a better than 1:1 ratio for karma exchange between each other, then why the hell aren't their pairs for Force 2,000,000,000,000 free spirits out there? The consequence of a better than 1:1 ratio is the ability for two spirits to exponentially increase their karma stores with each trade. Two spirits could spend weeks trading karma back and forth, accumulating trillions upon trillions of karma each.
Lets say, for example, they have a 1:2 ratio. Spirit A give 1 karma to spirit B but Spirit B receives 2 karma. Spirit B then gives that 2 karma back to Spirit A but Spirit A receives 4 karma which is given back to B who receives 8 karma which is given back to A who receives 16 karma which is given back to B who receives 32 karma and so on.
2:3 is slower and requires a bigger seed but the results are the same.
