Worm Gear Ratio

I am new here and just starting to gather parts for my rotor build.
I was wondering if anybody can tell me what the gear ratio is for the worm gear assembly.

According to this post it’s:

36:20 = 1.8 (from pulleys) and 30:1 = 30 (from worm gear-worm wheel), 1.8*30 = 54.

That sounds about right. I was guessing the worm gear assembly was 30:1 by its self.
I guess if I multiply the total gear ratio of 54 by the drive motor torque that would show
the final torque of the mast shaft.

So if I am correct the stepper moves 54 turns = 54*200 steps for one mast shafyt turn??
