NHC progressive handicap

Progressive handicap (NHC1): each boat’s TCF is updated after every race based on its finish, so fast boats acquire higher TCFs and slow boats lower ones. Race N+1 uses race N’s updated TCF. The blend factor α controls how quickly the TCF responds to each race’s result.

Examples

#	Scenario
1	NHC1 — single race, SWNHC2015 blend with one slow-extreme boat
2	NHC1 — non-finisher carries TCF unchanged into next race
3	NHC1 — competitor without starting TCF is rejected; sub-MinFin suppresses update
4	NHC1 — multi-race: race N+1 uses race N's newTcf as tcfApplied
5	NHC1 — Puppeteer HPH R1, Sailwave SWNHC2015 verification (n=14)
6	NHC1 — per-fleet profile override (aggressive blend rates)
7	NHC1 — H17 HPH multi-race: realignment anchors to base ratings (Sailwave-verified)
