PBN kicks in, when another link is placed?

I may have seen some strange behavior, or just having a hard time. I always used authority links on my pbns before posting my money sites backlink.

But I have noticed that if I place +1 authority backlink after them, they are really kicking in.
Is anyone noticed something similar?

Could be just a coincidence. How many times have you seen this happening?

maybe that 1 authority link when got indexed forced to crawl the changes?

Have you tested this behaviour with different keywords/ authority links?

No, the backlink has been already indexed. I have placed the money-articles long ago.
We are alking about 18 clean domain with average RD80, waited 1 month to age, placed brand/url anchor.
Than nothing happened for about 1,5-2 months.

No, just in my niche.

Just now, I have started to working on my existing pbns, placed some another article with authority links. A week later, noticed some positive moving in serp.

Maybe thats just crazy toughts, but for google that could be an easy catch for 99% of the new (really private) pbns.
Just make some algo for "devaluate the last placed backlink on sites", and all done.

So right now of course, that could be anything.
Thats why im asking if it is possible, and if anyone has seen this behavior before...
