On May 15th, it is planned that Mana purchasing rates change to circa 1$ = 1,000 Mana and that all the pre-pivot data about Mana is multiplied by 10, including profits on leaderboards.

My take is that as a result, rankings in Leagues will get almost frozen due to differences in previous earnings being multiplied by 10. Let's see what Manifold thinks about it.

If the new purchasing rates are postponed, the actual date when the now rates take effect will matter for this market. If it takes effect in-between two seasons or a the very begining / very end of a season, this market resolves N/A.
