Ugh. It's complicated
https://skyandtelescope.org/astronomy-news/how-astronomers-count-sunspots15022016513/
because not everyone has the same eyesight, count the same things as sunspots, and so on.

So they have a formula.
So they compare numbers from various observatories.
So they figure out it is a big mess but since it is roughly stable since 1700 - maybe it is okay.

Ugh.
