Why do the amount and level of trainers coming from Black writ invites fluctuate in X?

Question

I've unlocked Black writ and it was awesome at first, tons of trainers and all stronger than Silver writ trainers. But now for the past 2 days, I'm still spending 300K for the Black writ but I'm not being flooded with battles anymore and at least HALF of them are low level Baron's. At first I used to get mostly Duke's, Duchess' and gym/elite 4 trainers with lvl. 70 and above Pokemon. I still do but it's not nearly as often. Why is the game doing this suddenly? I went back to sending the Silver writ and it works perfectly as it should, Black writs are the only ones coming half assed.

What does 'writ' mean, exactly?

Answer 1

From my personal experience I've found that it sort of resets or goes in a cycle. Low Barons-Grand Duchess and then back.

This process speeds up the longer you stay at the Chateau battling people and if you even let one escape let's say that afteer 5 hours you return and everyone has changed then you might have to start all over since you weren't battling anyone and the movement in the Chateau continued.
