🏊 A Line of Classes

Para swimming classes S1 to S14: an ordinal scale, why S5 is not half of S10, and comparing times fairly.

A line of classes

Para swimmers race against swimmers with a similar level of impairment, so races are fair. Classes S1 to S10 are for physical impairments, from most impairment (S1) to least (S10); S11 to S13 are for visual impairment, and S14 for intellectual impairment. In breaststroke many swimmers race in a class one lower (SB).

Which class is for the most physical impairment?
