I'll give this a try. My typing is better when I use slide to type but I'm still super uncomfortable with it (I feel anxious trying to think of the letters "fast enough" even though I know it doesn't matter).

FWIW I've felt my phone typing accuracy has gotten worse every single year for, whatever, almost 20 years now. That's not the case on the computer.

I almost exclusively use slide to type and what I do is not think about the letters, but about the motions I would have done if I was typing with my hands on a regular keyboard, sort of letting muscle memory take over and create the correct “shape” of the word without thinking too hard about it.
