This is very interesting!

Your post opened many questions in my head. For what I know, the AI, in a same session, learns from every run that you are doing... that's why for a same prompt or very similar one, it keeps the same style in all the artworks. But never thought that the series of runs could be connected following some kind of timeline. The amazing is also, that you got such timelining in different sessions... when I start a new session, most of the times, the AI takes a particular style, different from another sessions, using even the same prompt in all of them. But that is not what happened to you, so I think should consider again my previous assumptions.

Thanks for share your experiments and thoughts with us!
