Maybe phrased squares can be a bit faster than contras because there is more resting (to catch your breath) in squares, waiting while the sides or heads do something...

Folks,
I am curious.  Tempo for contra is often below 120 bpm.  I learned to call
squares at about 128 bpm.
Is this significant difference the norm, and if so why?
