First I heard of this, very interesting....... is this because of more magnetic flex in the square steppers?

Holding torque is dependent on motor frame size, stack length and
whether it's round or "square".
Generally round motors are:
NEMA-23 50 in-oz per stack (stack = 1, 2, or 3)
NEMA-34 150 in-oz per stack
NEMA-42 600 in-oz per stack
"Square" motors generally have twice the holding torque of their
round motor equivalents.

1 ohm. The "holding torque" was a good 185 ~ 265 oz./inches,
depending on how it was wired. So back to my question, can one
assume with simular specs, there would be a simular holding torque
for other steppers?
