The parser had Free/Back/Breast/Fly/IM/Form/Pull/Choice in its STROKE_PATTERNS. Real coach input contained 'kick', 'drill', 'fists', 'catch up' - all missing. Adding two vocabulary entries (kick, drill) lifted the bench score from 0.20 to 0.42 in one iteration, more than any algorithmic fix in the loop. Real-world vocabulary gaps usually dominate algorithmic complexity in parser work.
