Note
A plural that only some meanings of rotation can take. The steady act of turning is uncountable, so the plural begins once turns are counted as full cycles. It also covers duty rosters (staff rotations), shifts of investment between market sectors, geometric operations that fix a point, and a baseball club's starting pitchers. Comparing rotations across a league therefore means comparing several teams' pitching staffs.
