So I think a really interesting question is what's happening physically
when we experience "supporting" our partner as was described upthread and I
had a thought but I'm not convinced I'm right.
To be stable, the torque also has to be balanced. Not the torque around the
flagpole axis, but around an axis tangential to our line of travel through
our individual center of mass.
The torques we need to balance are the tension between the two dancers and
the normal and friction forces from the floor.
I think generally the connection point is above the center of mass. Our
centripetal force has to be pulling us inward. Let's call this positive
torque.
To counterbalance this (and thus keep us from having our feet fly out
behind us) we have two options. We can move our center of mass farther from
our partner than our ground contact point so that the normal adds the
counterbalancing torque, or we can add centripetal force from the friction.
I suspect we do a little of both, but I think a good feeling swing is
mostly the leaning back a little solution (i.e. using the normal)
However, if we teach people to lean back to five weight, they might over do
the lean. At this point, the normal torque becomes much higher because of
the higher effective torque radius. To keep from falling over, that means
we have to add a whole bunch of either extra tension force OR friction
force pushing you apart. Or both.
At this point we have to jump back to the force equation again. If we're
swinging fast enough, the extra tension force becomes our centripetal force
and we're doing a really fast swing and just leaning back a bit.
But if we're not, then we need a whole bunch of that friction force pushing
you apart. But that's the opposite of the force your connection is
providing.
When I think of swings where I felt like I was holding up my partner, I can
remember having to push back away from my partner with my feet. All of a
sudden I'm providing two forces that are cancelling out instead of helping
me spin.
It is also possible you're pulling up as well. That will also cancel the
torque.
This all assumes rigid body physics (which is not the same as rigid bodies
biologically. More like having an active core biologically.)
More thought is needed.

Thank you, Jeff, for venturing this calculation.
I've been meaning to try
the numbers for some time. I got as far as doing the equations in my head
last night, but couldn't put in numbers before falling asleep.
Chris is right about the factor of two in the equation for the masses.
Think about the center of mass of the whole system. That is the motionless
point you are turning around. In a previous thread someone compared the
effect to holding onto a fixed pole and swinging around that. The same
centripetal force would be needed to keep you on track as though you had an
equal mass partner with equally long arms. Replacing the pole with a
partner does not change that force.
Chris also makes the good point about that centripetal force being
provided by two arms or even four arms in a barrel hold.
Thinking about the numbers, let's look at the distance traveled. Suppose
the radius is 1 foot. The circumference is a little over 6 feet (2*pi).
4.5 revolutions would be a little over 28 feet. Doing that in 12 beats
(steps), not allowing any time for stepping in after the balance or opening
up after the swing, means 2.4 feet per step, which seems long to me. I'm
guessing that a two-foot separation of the dancers' centers of gravity is
incompatible with 4.5 revolutions in 12 beats. Also, that's a 135 degree
twist of the planted foot on each step which may be aggressive for most
dancers in a swing.
Looking at the contribution to the centripetal force from the feet, it's
important to note that the friction force there is applied much farther
from the dancer's center of mass vertically than in the case of any arm
connection. If you weren't holding on to your partner, you'd need to lean
in a little to keep your balance, while an earlier theme of this thread was
increasing the separation between dancers. I'm getting away from
quantitative here, but note that if you are turning 135 degrees with each
step, you want low friction which may limit your ability to apply a
centripetal force with your feet.
It's complicated.

I had poked around with the math as well, but struggled with all of the
estimates. I'm happy to see Jeff taking a stab at this and discussing.
I think likely some of that force is taken by core muscles, and
transferred to the feet against floor, and such.
This would be a really cool practical kinesthetics research paper!
