Twenty yards to sixty-five yards at five-yard increments doesn’t sound to tough. Go shoot these distances and you’d discover it is pretty tough.
What might become clear is: You can drop points at 20 – 30 and gain points at 55 – 65 yards. Or you can drop points at every distance. Or you can hit the center at every distance. In other words – it is tougher than one might think.
Shooting set distances even 70 meters isn’t as complex as shooting multiple distances. Seventy meters is a long shot (@ 77 yards) but you’re set and can make corrections should you be off a tad.
Shooting an international round you get three shots per distance and move to the next target. So your sight must be spot on.
Say you shooting 55 yards and the arrow on your elevation scale looks like it is in the correct position. The needle on the elevation block has a diameter and can cover your calibration mark and still be a few clicks high or low. If either is askew despite a flawless shot execution the arrow will be off the mark.
Walking through a forest, on and off of fields, and through mixed shade will have an impact on lighting and center placement of a shot. Chances are it won’t be horrible but light can still impact aiming.
Then, there are, at times, the potential for a shift in target elevation. When the angle becomes significant aiming at your usual center will float your arrow high whether shooting toward a downward set target or an uphill target. Shooting a set distance, such as 50 meters (compound) or 70 meters (recurve) this isn’t an issue.
When preparing many archers focus on improving their long shots to the neglect of the shorter distances. The result can be slight improvement at the long shot, over confidence at shorter distances and overall less than optimal scores.
To prepare build a training plan. For example, practice twice a day once in the morning and one in the afternoon. There are ten distances. In the morning pick a short or long distance and shoot 100 arrows. For the afternoon shoot another 100 arrows at the reciprocal distance. Over 5 days you’ve shot 1000 arrows at 100 arrows per increment. Then on one of the two remaining days do practice International Rounds – one in the morning and one in the afternoon. With warm-up shots this is going to put you in the range of 1200 arrows per week. (Your shot count can vary depending on your time available for practice) The last day is reserved for recovery. Start your international practice as far in advance of an International Competition as feasible in consideration of your event schedule. (If you’ve been shooting less than 100 arrows per day adjust your load to prevent an injury)
