Non-stop dancing on certain KWs since May update. Anyone else?

Overall my website traffic has experienced across my sites following Google's May update.

However, I'm seeing crazy movements in three fairly valuable KWs with (2-5k monthly search) that used to rank in pos 1-3.

The first two graphs are from niche website 1 and are two pages which cover two extremely closely related terms (think best black leather shoes vs best brown leather shoes). The second one isn't dancing anymore, it just dropped and is very slowly regaining positions.



The third one is from another website in a different niche:


It doesn't seem to be an issue with Serprobot, I notice my result is either missing or there when I run my own searches.

Anyone else noticed something similar? Could it be some kind of algo penalty?

Didn't know you could check weed on GSC. Is that a new feature?

yes premium publishers and current agents of google can, you’ll have to give up BHW secrets to access it

I'm experiencing the same. I have a bunch of keywords on weed. They've been dancing since May 10.
