Detlev, You have made a very good write up for this information. I did have a question about the target clearance 2.5.6. With target size stated as 9 mm in 2.5.5, a Center spacing of targets of 9mm would not give any space between targets. Please confirm if I have read your information correctly or not. Best Regards.
