Barest example of question if Ship Rig is 13x or 10x came up this weekend
. The 2nd rig compresses the tail towards the loop for more power, so the output is 2x, not 1x; like the output from the ship rig is 13x not 10x. The equal and opposite reaction is captured and harnessed in to pull on the target work load in each case. Giving a compounding action to the 'single pull'; by employing it's promised equal and opposite forces to place more positions/points/lines of pull on the load.
