Title says it. I have had a great time improving my accuracy recently and have been able to narrow it down to an 85% hit rate on a 1.5 foot wide and tall target from 5-7 yards, and on a good day can get 60% at 10 yards with most just barely missing. This is being done with 3 concepts in mind before every throw ; 1.Stance 2.Angle of swing 3.Feel the pouch.
However, I am struggling to get any more accuracy than this, anybody have some tips? My goal is to get an 80% hit rate at 10 yards on an average day on the same 1.5 foot wide target, which I'm finding to be quite difficult even with throwing at 80% power instead of 100%.

Thanks in advance.

P.S. a video of target practice, but should give u an idea as to my slinging style. https://youtu.be/DNCzkFT07dw

Do you have a video ?
Otherwise, what style do you use ?

Stop counting the successes and tryhitung a much smaller target

I found this video helpful for accuracy. https://www.youtube.com/watch?v=6irNkhLdApk

What Mersa said works well.

Good luck! ;D
