Getting a little confused.
I decided to add a pulley on the go-between part that rotates at a 1:1 with the input and output.
I measure that to the output and I get close to a 1:1 value, that is 1000g of pull on the prime mover needs about 900 to 950g on the resistance side, either direction of rotation.
I measure that to the input side and I get a much larger difference, that is close to 1200g for the prime mover needs about 900 to 950g on the resistance side, either direction of rotation.
I was getting a difference one way when measuring between the input and output, then I advanced the output and locked the output in place and now it is close to a 1:1 either direction.
