We are pretty much entirely in agreement here.

I've often wonder what the effect of changing g levels would have in
a multi-deck design, or even without multi-deck but good access to 0g
at the center. Although real research is necessary to get the answer,
chances are it's not a problem. We already has 8-9 hours of bed rest
a day, and bed rest is routinely used for 0g simulation on the ground
to study human response. True, the studies put you slightly head
down, but it's not that far off.
