This method doesn't seem bad.

Realistically, LLMs write code much better than most people. In my domain, there are areas where I still write better code than an LLM, especially when it comes to physical constraints it might not understand, but there are far more domains where the LLM writes much better code than I do. In that sense, writing code with an LLM and keeping track of it feels more helpful than I expected.

Practicing solo coding for an hour a day often ends up being mechanical and not very useful. This might actually be more helpful.
