Just for clarity: From my perspective this is okay to go in as-is, the remaining ToDos (e.g. deduplication, comments) could always be done later.

I'll approve the PR so that my "Changes…

@sherholz Ah, thanks for the input. I wasn't too familiar with how this works internally. I'll look into adapting it.

New update:

With a slightly different constant, max error is down to 1.55e-6.
