Scoring Methods

Note: all times are local, 24-hour clock

PHRF_ToD:  PHRF Time on Distance

Corrected Time = Elapsed Time seconds - (PHRF Rating * course Length nautical miles)

Seconds Behind is shown as Seconds per Mile

Pursuit_PHRF_ToD:  Pursuit Race, PHRF Time on Distance

A base Rating is established for the race, usually the highest (slowest) rating of a boat in the race.  That boat starts at the nominal race start time, then all other boats start at the nominal start time plus the number of seconds calculated by:
((base Rating - individual boat PHRF Rating) * course Length nautical miles

Seconds Behind is shown as Seconds per Mile

PHRF_ToT:  PHRF Time on Time

Corrected Time = Elapsed Time seconds * (650 / (550 + PHRF Rating))
(also see http://offshore.ussailing.org/PHRF/Time-On-Time_Scoring.htm )

Seconds Behind is shown as Seconds per Hour

Portsmouth

Corrected Time = Elapsed Time seconds * (100 / Portsmouth Rating)

Seconds Behind is shown as Seconds per Hour
