RULE NO 5.

Play the percentages and always dope for a safe ten. Remember, they count the points first.

There is a sub-set of rules to go along with Rule 5, and these are derived from the logic of probabilities. If the wind is quartering; i.e., 8 to 10 o’clock, or 2 to 4 o’clock, and moderate to heavy, the most probable change in condition is a velocity change. Therefore by slightly over-doping the drift as noted on the sighter, a safe ten will be assured for either a small pick-up or let-off from the original condition. Conversely, if the wind is blowing from 11 to 1 o’clock or 5 to 7 o’clock, the most probable change is an angle switch. A slightly underdoped hold will minimize the changes of getting caught in the switch. If the wind is light to moderate, these rules do not apply because a small change represents a larger percentage of the original condition. In this situation, the hold should be as indicated by the drift on the sighter. Using the safe ten approach to doping may initially produce a lower X count. However as experience is gained, confidence increases, and eventually your shooting should result not only in higher scores, but more X’s also.
