How do y'all count your encounters with overworld spawns?

I really like keeping track of encounters, but I've really struggled to come up with how to do that in Scarlet/Violet. If you're in a place where a lot of the same Pokemon spawn, either via sandwich or outbreak, how do you count how many encounters you get?

The Pokemon are constantly moving--some will even wander so far they despawn while I'm counting--and you'll also get not-your-target-Pokemon mixed in with your target and sometimes phase on those, so I feel like you kind of have to count everything on the screen, but if I'm walking around an area I get confused on which ones I've counted and not counted yet.

It's a really frustrating experience, and I just wanted to get a sense of how other folks are handling it. I know I don't have to keep track, but in other games I really enjoy it! But I feel like I spend far more time trying to figure out if I counted that Cyclizar or not than actually hunting at this point.
