r/Cornhole

So I've been playing at a local weekly cornhole club and I've gotten better than when I started but I'm incredibly inconsistent. I can throw a 4 bagger and then throw for 2 points the next round. I don't have boards or the space to setup at home to practice outside of the weekly club tournament and I'm honestly not even sure "how to practice."

I feel like I need feedback from someone who knows what they're doing.

I currently throw with a butterfly grip but I still struggle with throwing a consistent flat bag but I'm not sure why.

Sometimes the throws that "feel" the best coming out of my hand actually are the worst and those that feel awful go right in the hole, so relying on my own feedback seems poor.

Obviously without a consistent flat bag or consistent shot, I can't work on any other shot shaping so I struggle with a dirty board pretty heavily. I've somehow thrown a roll bag but I honestly couldn't tell you how.

Really just looking for advice. For those who went from beginner to intermediate to advanced, what did you do? Tips for practice? How to get good feedback so I can actually work on my throw and then advance my game.

Anything would be greatly appreciated! Thanks
