Poly Hive, have you actually read the article as published in ABJ? Part 1 can mostly be ignored but part 2 has some very intriguing statements.
So the reason for bees cycling from the outside to the inside of the winter cluster is not to warm up, it is so they can dry out from all the excess water they produced when they were in the outer shell.
In a highly insulated hive, net water production falls short of needs. When too many bees become water deficient, they fly out in a desperate bid to forage for water.
Edit to add that Mobus defined a "normal" winter colony as 10,000 to 15,000 bees. This is enough to cover about 4 or 5 Langstroth frames when clustered.
these bees were found to be evaporating more water from their bodies than they produced as a "waste product" through their metabolic conversion of honey sugars.
Bees in the warmth of the central region (of the cluster) have a lower metabolic rate and will produce less water than they are evaporating.
Bees in the outer shell (of the cluster) will generate more heat energy, will consume more honey, and will, consequently, accumulate more metabolic water than they can evaporate in this colder region.
Moving into the center (of the cluster) in order to dry out is the solution for bees of the outer shell
When the hive is too insulated and too warm for a mild climate, thirst-crazy bees were driven out to fly at the slightest excuse; not to gambol in the sunshine, but to collect water.
