Your source (~4:12) definitely looks like a regular counterbalanced funi. Also, we’re not talking about the overhead cable here, right? Because I mean the other one. The one where you can even see wheel-thingy turn as the cavle moves. (No idea what English name for that is)

A meaninglessly pedantic distinction in the real world *but in this house we commit to the bit

And that’s exactly how it should be 😄
