Model carry-in

Jerome Kym sits in the top tier band of active ATP-tour players by our weighted Elo measure. On clay, the model rates them below their overall number — a surface where their price routinely overstates them. Pressure profile: tour-median. We use this to size break-point and tiebreak edges in close matches. Career record in our database: 136-73 (65.1%) across 209 matches — hard 56-31, clay 73-36, grass 1-1. Live numbers (weighted Elo, choke index, projected hold, full service profile, recent form) refresh nightly and are visible to subscribers.
