ECHO — multi-race handicap propagation across two races

Scoring system: ECHO α (blend factor): 0.25

Three boats over two races. Verifies the running handicap map: race 2's
applied handicap is race 1's new_H. Engine matches the IS PI formula at
every step.

Initial handicaps:  Alpha=1.000, Bravo=1.020, Charlie=1.050.

Race 2's tcfApplied for each boat is race 1's newTcf — the
      propagation contract.
