One of the things that makes the Royal Canadian Henley Regatta unique is its scoring system for the Efficiency Trophy. This trophy is awarded to the Regatta's most successful club. The current Efficiency Scoring System was designed and implemented in the early 1970's The fact that the larger local clubs could send more competitors to the Henley and would consistently win the Maple Leaf Trophy (the total points trophy at the time) by sheer volume became an issue. It was decided that a change was required to allow smaller clubs to compete to win a Henley Regatta. A committee was formed to study the problem and the result was the scoring system known as the Efficiency Trophy and in current use.
The Royal Canadian Henley Regatta Henley is a Club regatta, so the points are accumulated by the club. Points are based on the Canadian Scoring System.
There are no points awarded for Heat Winners at the Henley. The better a club places in the final races, the better their efficiency as a club. Some baseline rules are applied to make it fair. One should not be able to enter a single crew in one race and win it, thereby having 100% efficiency and winning the trophy. A club must participate in at least four (4) Final Events. The Club must enter at least fourteen (14) Competitors who row in these events and they must participate in at least one (1) Sweep Oared Event and one (1) Sculled Event.
"Actual Points" are the clubs actual finish position points which are totalled. "Possible Points" are calculated as if the club placed first in each of the final events and are also totalled. The "Efficiency" is the percentage of Total Points divided by Total Possible Points. The club that qualifies, and is the most efficient in it's over all entries throughout the regatta, is the winner.
Total Actual Points divided by the Total Possible Points = The Efficiency Percentage.
If a club has more than one boat in a race, the "possible points" are calculated as 1st, 2nd, 3rd position scores, since only one of the boats can place first.
For example if Club A had 3 boats in a Pairs Race, their possible points would be for 1st, 2nd and 3rd (15 pts + 8 pts + 5 pts = 28 pos pts). If they placed 1st, 3rd and 5th ( 15 pts + 5 pts + 3 pts = 23 act pts) their efficiency would be:
Club A: 23 Actual Points / 28 Possible Points = 82.14% Efficiency
Clubs B & C placed 2nd and 4th in the same race their points would be:
Club B: 8 Actual Points / 15 Possible Points = 53.33% Efficiency
Club C: 4 Actual Points / 15 Possible Points = 26.66% Efficiency
