Advanced Swimming Kinematics
Calculate stroke rates (SPM), model distance per stroke (DPS), evaluate SWOLF efficiency scores, breakout speeds, and hydro-dynamic drag suit resistances.
Configure Parameters
Underwater dolphin velocity should be higher than surface swimming velocity. Breakout exactly when drag matches surface swimming velocity.
