I seem to be in equanimity territory in a semi stable way, though I have to back off from my life quite a bit to settle into it. Can't face the stress of responsibilities TBH. Suddenly a lot of what's written in MCTB2 is a lot clearer. Acknowledging the value of the book.
I hadn't really realised that equanimity is 4th jhana because of the way it's mapped. I thought it was something way after, because it has it's own special name. Or that the formless jhanas are aspects of equanimity, which I guess really means aspects of the mind but more obvious from equanimity.
As to fruitions I still don't know if I would recognise them even though I was at the three doors years ago.
Anyway, yeah, good book.
