video description :
"Max slinging range 90cm sling, 40°C, all kinds of stones.
When I'm there slinging I can't see the stones land , I only see them until they start to fall and the streamlined small stones suitable for max range disappear from view even sooner.
I need to train to throw even heavier stones so they are visible further."

I think this is my first and most certain evidence that I sling over 200m
P.S: Countless throws didn't make it to the final video because nothing can be seen even though a lot of them were vertically oriented to the center of the camera view.

    If you want to have some fun try slinging golf balls if you haven't done so yet.  As long as you can get a pure backspin on them they will fly over the hills and far, far away.

one jump on the back leg or just stride,  I had a little less than the width of a road so I couldn't do a run up.

Mersa

yes
(edit: these measurements were done with google earth)
1st position
  1st hit is downhill 17m
  2nd hit 22m
2nd position
1st hit is uphill 18m

not easy to find flat place clear of life around here

Mersa, it's more rolling than up or down.  It is lower but not by much.
