I may or may not have mentioned this before, but one thing that played a major role in my renewed interest of slinging was the game Dungeons and Dragons. And now I am about to reveal what a complete dork I am

A while back my brother and I decided that it would be fun to write out what we would look like as d&d characters. My brother found out quickly that english proffesors don't translate well into an adventure game, but I did alright. Anyway, I was drawing up a picture of what I would look like and how I would carry my gear, using things that I actually own, and I had drawn myself with a bow. Now, I don't own a bow, but I'm ok with one. The more I thought about it, the more I thought that I should limit myself to things I actually had, or could afford (or make). And that's when slings popped into my head. I went to the internet and looked up slings, and now here I am... but enough of the backstory.
What prompted my post today was something myself and the other supervisor here (who I have converted to slinging) were doing saturday morning while waiting on all our peons to show up for work. We had a foam practice golf ball, and we were slinging it back and forth at each other. On impulse, I tried slinging at him while I was running, and to my suprise, I hit him. I tried it again several times with good results. He being also a d&d fan, joked that I had taken the "shot on the run" feat. If you're not a d&d fan, that probably doesn't make much sense... sorry, if you really want to know about it I can explain.
Which brings me to this morning, and the real point of all this. I was back in the warehouse practising my slinging with a raquet ball, and I decided to try my shot on the run again. My target was a 1qt canteen sitting on the rungs of a ladder at about 12 yards. I managed to hit it 75% (15 out of 20) of the time, which is better than I do standing still. I'm wondering if by running and not really thinking about my shot much, I'm actually improving my chances, or if I'm just finally getting better.
Incedintally, that drawing I did of all my gear played a role in me changing my slinging style as well. I love my figure 8, and I still use it for distance or fun, but I've changed to the byzantine style for accuracy... mainly because the pouch would get caught on my sword during a fig-8
