I know several descriptions of the experience of the PoI for "dry" insight practitioners (like Mahasi style), but none for jhana practitioners (for example, someone that does sits of 30 mins jhana practice, Leigh Brasington style, followed by 60 mins vipassana/noting/choice-less attention/etc)

Do you know how the jhana practitioner experiences the progress through insight stages differently?

For example:
- faster or slower? (I remember Daniel Ingram somewhere saying slower)
- more or less intense?
- any particular nanas that are experienced differently?

The main difference is that the content is experienced less emotionally and more energetically in jhana.

Emphasis on less, as you can have some pretty intense death-like experiences in J3, as many here can attest.

Daniel explains this here:
