You just exampled a "plurality" = largest subset of the total set.This is still not clear. FD stated that there are more players in Open compared to OTHER modes.
So it can be 40% in Open, 30% in Private and 30% in Solo. Meaning that 40% in Open and the 60% is divided in solo/pg.
FDev stated "Majority" = largest subset is greater than half of the total set.
