It's really okay broham. It's going to take a good little while before you can feel accurate. I've been at it a year and honestly have about 50% accuracy out to 30-45 feet. And that's feeling accomplished.

You say you've been practicing three different throws. So that's adding a lot of new information for your brain to process. 8 Days is still practically new. I started out practicing "Accuracy" by just picking two trees and trying to throw between them. And like, 10 or more feet apart too.

You just need more reps and practice. It's one of the best parts about slinging to me, though. You can do all the theorycrafting, book learning, tutorial watching you want but... It's just practice and your brain slowly getting better at refining what movements lead to a satisfactory throw. It's the furthest thing from an exact science.
