A coach pushed back on a proposed 4-value suit_type enum (none/jammer/textile/fulltech) with a simple observation: "Usually one or the other, so it is quite binary." Modeling distinctions nobody actually makes creates data-entry friction, spurious aggregation buckets, and false precision in downstream analytics. The simpler boolean matches the actual decision a coach makes moment-to-moment, and the resulting schema is easier to query and reason about.
