Handicaps are useful for tracking progress when shooting different rounds each week. These tables use the method devised by David Lane to produce the tables published by ArcheryGB. Tables for non-standard rounds can easily be calculated and some rounds eg Frostbite, Burntwood and the new metric rounds for juniors have already been added.
The main reference on the calculation of the 1995 handicap tables is:
Using the "non-standard round" (last entry in the drop down list) you can work out the handicap for each distance shot to find out if you have a weaker distance that you need to practice.
The basic form of of handicap competition works well within a club, each archers handicap is used to work out an allowance for the round being shot which is then added to their actual score. The winner is the archer with the highest adjusted score. The allowance is the archers handicap score for the round subtracted from 1440. So in theory everyone should end up on 1440, unless they shoot better or worse than their handicap. No adjustment is needed for round, bow type or gender.
With an open competition the archers handicap is not always up to date or available, so the handicap is often calculated from the first 2 dozen arrows shot in the round. This gives an advantage to those archers that start slowly, but finish strongly.
Rounding the average scores, or 1 decimal place.
There is often some discussion about using thick line cutter arrows indoors to improve scores. The standard handicap tables are based on 18xx arrows which are 7.14 mm (18/64 inch) in diameter. Use your handicap to find the average score for your actual arrow diameter, then change to the thicker 23xx arrows to get a new score for the same handicap. Note: 9.3 mm is the maximum diameter for most bow styles, and 24xx are 9.5 mm. Biggest gain is on the smallest targets, for WA 18 metre you gain up to 5 points over using your thin outdoor arrows (5 to 6mm). For a Portsmouth the gain is at most 3 points, but you might lose much more by having arrows that are hard to tune and shoot.
