4/5 times I can easily get 100s of lines output, that only needs a quick once over.

1/5 times, I spend an extra hour tangled in code it outputs that I eventually just rewrite from scratch.

Definitely a massive net positive, but that 20% is extremely frustrating.

That is fascinating to me, i've never seen it generate that much code that is actually something i would consider correct. It's always wrong in some way.

In my experience, if I have to issue more than 2 corrections, I'm better off restarting and beefing up the prompt or just doing it myself
