The distance videos are taking a long time to cut together, but here's Part 1!  The video was running long and I decided to break it up.  Hopefully I'll have Part 2 ready in a week or so.

Once I get everything done and available to view, specifically a spreadsheet with all the results I collected, it shows a pretty interesting picture coming together.

*Update* - Part 2 is complete and posted: https://youtu.be/iN4tm7JcZu4

Doing a spinning hammer throw/discus spin before launch helps me with distance on uncomfortably big stone lobbing.

I think, 500 grams, 100 meters is attainable

my first thought was.
why not throw all the stones in one go working up the weights.

Then for measuring you just walk out to the furthest and measuer all the others on the way back.
With a carry bag to put the rocks in once measured.

But I'm either lazy or efficient - depensing on your point of view - and like to make things less effort as a matter of course lol

The other thing was: cigar fest ? really, lol

I'll watch the rest later

Part 2 is ready to go: https://youtu.be/iN4tm7JcZu4

It's linked in the Description of the video, but I'll put it here too.  Here's the spreadsheet with the measurements of all my throws: https://docs.google.com/spreadsheets/d/1FWV9c5y8HIF-mi67w21Pt60YM6czjEp2ETQ40tHr...

I did, but those throws were not in the video.  They are on the spreadsheet and labeled as one-handed.  Just for the 1400g stone though.  The distance one-handed with the 52" sling was longer than the average (with two hands), but shorter than the farthest two-handed throw.  I only threw one-handed twice, so the sample size is extremely small.  Not nearly enough to get anything conclusive.

I hate to say it, but with all the hours I put into this, I ended up with way more questions than I had at the beginning.

Here's my biggest question.  Does the maximum distance a person can throw with sling have two peaks?  Let me explain, and sorry if this gets confusing.  The stone I was able to sling the farthest was 765g.  The stones before and after it were 566g and 991g respectively.  Now let's say for argument sake that the stone weight I can throw the farthest of all is 150g.  (I feel safe using a 150g stone as a hypothetical longest distance weight because my farthest throw with the 765g was around 55m, and I know I can throw a 150g stone farther than that.  And that's all that matters for this comparison.).

So if we had a graph showing the average distance I can sling every stone in 5g intervals, my highest peak would be at 150g (because that's the hypothetical longest distance I've got).  After that the distance would start to drop down, and then there would be another peak at 765g.  Why?  Logically I would think the drop in distance would follow a pretty smooth curve.  But is there a point where the strength to throw a (large) stone along with the stone's weight reach a peak efficiency?  And if that's true, where is the point of least efficiency between 150g and 765g?

Sorry to dump that here, but it has me extremely curious.  Definitely a topic for the Math section.

We'll see.

Exactly!  So how my most efficient weight was around the 765g mark, this would be a bit different for everyone.  Where ever the point is that the speed isn't attainable anymore.

I like this analogy.

I would try a shorter sling, max length extended arm to your other elbow. I find when I exceed this length it doesn't help much

and pirouette
