Sometimes there is just too much talking. What C_A is saying should be fairly simple.
You stand on the one side of a field at a demarcated area and hopefully sling to the other side of the field where there is a open landing area for the projectile. Have one or two people stand at each end of where all the action is. Then you measure between the two points and that is it. You do not realy have to have other slingers to validate the effort, grab your nearest bobby, mounty, policeman, church minister, doctor, laywer etc, etc, etc to validate your effort according to the rules laid down at slinging.org and post the results page (downloaded from slinging.org) with the appropriate signatures of said people on it.
Any body could fake the result and signatures, so nobody would know, but since we do not get any monetary rewards or any reward for that matter, you would just be kidding yourself. (I know some golfers like that)

Coenie.
ps. Wind factor and ground slope should be discussed. I recon 2m/s wind should be OK, ground slope?
