Going to fourth density? Or fifth?

Are you saying that, for the time period between "full instreaming" and "full activation" there is a 3D/4D hybrid sphere just as there are 3D/4D hybrid bodies?

Yes.

When, in relation to this sequence of events, do you think is the end of the 75,000 year cycle when "all are harvested regardless of progress"?

End of 3D is not exact, like the beginning of 4D. The harvest is during the end of the 3D cycle or 75,000-76,000 years.
