Get someone to measure the height of the front sight when you are shooting at 10m.
The target at 5m needs to be positioned so that the front sight is at the same height as it was when aiming at 10m.

Your point of aim should be higher than the regulation 1.40 m when you shoot at reduced distance. Using trigonometry, I came up with a formula that will tell you the height of the target center necessary to maintain the same arm position you use at 10 m. The formula is:
TH = [(10.00 - SD)/10] [EH - 1.40] + 1.40
Where TH is the adjusted center of the target, SD is your shooting distance, and EH is the height of your eye when in shooting position. For 5m the formula reduces to
TH = 0.5(EH - 1.40) + 1.40
All measurements are in meters, with two decimals; ie counting millimeters.
