At the time I was shooting good scores on the back of the card as practice ( even managed a possible!) so thought, why do I need the aiming mark? Only because the match rules stop me shooting on the back of the card!
Hi Robin, Here is the solution to that

3. The shot "only" without aim.
The coach has to prepare a piece of paper 5 cm. x 7 cm. so. One side of the paper is to bend at an angle of 90 °, forming an edge from 5 to 6 mm across. This edge will help the coach to put the paper in the correct position. Seeing that the shooter is leveling the gun in the shooting, the coach put the bar up the paper and prevents the rear sight to see the target shooter. The shooter is firing without seeing the target, but he can control all the sights.
