Class Head-to-Head

Why this replaces “Teammate Head-to-Head”

A WEC car’s 2-3+ drivers share the same car via stint rotation rather than racing each other in separate cars, so there is no teammate head-to-head to tally. This instead tallies, for every pair of teams that both fielded a classified car in the same class at the same event, which team’s best-placed car finished ahead — analogous to a manufacturers’-championship head-to-head.
