It took me about a week or so once I dropped down to 34. Sometimes I would lose a key and that made me realize it needed to be moved if I couldn’t easily remember it.
One thing I found super helpful was configuring autoshift for non-alpha characters. So now I can hold [ to get { for example, or 2 for @. It’s helped a lot in reducing the size of my keymap. And as I said, home row mods are incredible once you become accustomed to using them.
If you’re interested I can share my own keymap, which might help you come up with some ideas that help you.
