To original question, device provides 3x Effort as stated.
>>2x on saddle + 1x Left hand that also is a system input.
.
As any tool, personal usage can immensely vary final results.
>>especially on nylon highway we are are not only the input, but the load as well (and most rigid framework thru system)
.
Also see right hand grab of cam so also get 1x of that
>>but perhaps of more importance is stabilizing body across and keeping CoG closer to line for leveraging own bodyweight less against your efforts, than if bod CoG falls further away from force/at greater leveraged angle as load...
.
Also see foot cam for more powerful leg muscle(s) feeding into the more powerful 3x / left hand side.
.
Another factor of the weaker arm pull(s) is a tension pull,
>>tension side force of effort will be urging CoG closer to rope, towards easier leverage thru the motion.
.
But easier leg effort is compression, who's side force , and impact of thrusts urge to press CoG to greater leveraged load angle against efforts as motion continued. It takes more effort to hold against side pressures, and even more effort if you do!
.
Smooth, non impact compression leg input , less than or not too much greater than in concert tension 2 arm pulls I tried to orchestrate towards for greatest efficiency, partially by limiting side force loading as could, and staying more inline as load to the force line in the rope support device.
.
CoG falling away from line @12 noon to bod 11 o'clock 30 degrees deflection places half of bodyweight sideways statically , and then half of leg thrust on motion while 14% more effort upwards also. Angle makes effort less efficient to target while fighting side forces. Body is device in position that many materials and devices fail from not being able to handle side forces, when can handle harder work inline part of inefficiency okay. Tension arm pull effort can cradle into better efficient position of less leveraged load against efforts. Chest roller can be great help too!
.
Found can be tough enough as scientific wrestler, to not further over work by setting self up to bull dog every point as a 'lazy'/no thought required strategy. Work don't really start until into play, flying around ring stinging like a bee anyway!
