"The people of Claddage in Ireland in the mid-twentieth century still competed with the sling, saying that to be a good shot one had to 'strike a shilling as far away as it could be seen' (Echols, 1950: 228")

Sounds about right.
If you're not good with a sling, you're never going to hit a 0.92" dia. coin at 100y? If you're skilled, then one could put the shots in the general area and get the hit after a few hundred or thousand throws, after all, no conditions are mentioned (in this excerpt anyway).

Or...
There's thick fog in Claddage.

sub MOA accuracy

I'd say 30m but it is a range that a hand thrower could hit it . The background color is important also
There is no a set distance or a set amount of throws. reminds me of "sling at a hair and not miss." or "hit any part of the face" is there a magic number that everyone agreed upon?

this one includes target and how many tries but not distance

when playing against another 30% win rate is okay but when competing with yourself or nature I think it can go below 1% and be satisfactory for humans

That's a good data point.  I'm going to try this as well as soon as I remember to do when I have the time and am outside.

Sarosh,  I like the way your mind works.

You hear something you're not sure about, so you just put it to the test.

This is excellent data.

Well done Sarosh! Certainly a step forward in solving this.

It was cloudy and rainy today, but I went up onto a hill today and wedged a 10 pence coin (silvery and close to shilling-size) into a crack on a flat bench over looking the escarpment. I walked back from the bench until I could hardly see the coin (which was silhouetted by the white sky behind). With the distance measured on Google earth, I found it was about 50y. The coin was shiny so I think if it was tarnished or darker, I would have seen it better.
I will go back on a sunny day and place it in front of a dark background with the sun behind me; this should make it a lot more visible.
As it stands, I think around 50 or 60y is about the practical visible limit, (which fits well with what you found).
Exciting stuff...

It's occurred to me that this could be a good, simple ranking system. Stick a stake in the ground that is split at the top to grip a sub-1" dia. coin (US quarter or UK 10p, valid), and set it at 10, 20, 30, 40, 50y. Each increment is different rank, and video proof of hitting it at the given distance, awards you that rank.
What I like about it is that it's not only a very compact and simple setup, but it's historically inspired and a comprehensive display of skill.
Anyone at all interested?

Thanks! that's a great compliment!

that would be interesting to see, all you need is to hit it once while filming, doesnt matter how many tries.

That chart is awesome Sarosh.  I love the idea of trying different colors too.  I'll try to put one together soon.


@Archaic Arms - In the setup of the contest you've described, do you think hitting the stake itself would disqualify a hit?  If not, I imagine a camera would need to be pretty close to confirm the coin is actually being hit too.  Just curious if you were envisioning the coin being knocked off without contacting the stake or not.
