One of biggest red flags that appeared almost immediately when comparing PHRF scoring with ORC scoring was the time differentials between boats and how those differentials played out in the final scoring results. It was not unusual for a time differential of over 5 minutes between boats would translate into a boat clearly winning by several hundred yards would end up losing a race, particularly in light air conditions. This raised the issue of wind conditions on various points of sail. PHRF cannot account for these variables and as a result does not yield accurate results. In fact, if you look at PHRF ratings and compare similar boats that have ORC ratings, the results bear no relationship to one another. ORC scoring can account for wind speeds between 4 and 24 knots!
