Getting back from a limb walk.

It's not perceived. Go set up a ring to ring in a tree. Find something that weighs about what you do and tie it on, and haul it up (skip the hitch). Then slap the hitch on and haul your self up, the hitch isn't magically making you lighter, what is? It's the fact the load is doing the hauling...
I do not own On Rope, I've read it a few times, but can't pull it off my shelf for reference. The knowledge you seek is out there, my son
 
By hauling you own ass up the rope you are effectively dividing your mass in half (both legs balanced), then to actually move up, you need to provide just a wee bit more force.
 
A Rads system is 2:1 plus a 1:1 redirect if the hauler is stationary. It is 3:1 if the hauler is moving. What has to be remembered or factored is the fact that the climber weighs less as he pulls down on the rads.

150 lb climber pulls down with 50 lbs, that means that the second pulley is only seeing the 100 lbs of his remaining weight. That 100 divided by the two lines are 50 lbs each holding him. 3 lines x 50 lbs is his 150 lbs. 3:1

Same guy but hauler is on the ground. Climber is still supported by 3 lines but his 150 lbs never changes because he is not exerting any energy. The ground hauler has to pull 75 lbs over the redirect to impose the 75 lbs to the 2:1.
He is not really a climber at this point but is just dead weight like any other load.

So this is based on the assumption that climbers consistently pull down with a force equal to 33% of their body weight?

33% exactly would be a free hang on a RADS system. 33% + anything the climber is going up. But that is splitting hairs. Can we go back to the up/down pulling thing? I felt like Dr Seuss there for a moment... How about we measure the force it takes to push a rope 1 meter.
 
Oh man poor Drew just wants to get back in from a limbwalk...down here we havd some crazy mushroom trees....long limbs low TIP's...I have always sucked it up and go out and come back balancing the shit out of it...get used to it...I am no superduper climber but get shit done....no mechanical advantage here....I setup a lot of redirects to save the long limbwalk though...pros of SRT

That's because your a real man, and we are just american'ts
 
I just bought a ascender because I find the thimble prusik annoying to load and then advance. However in most of the time I either just jump off the limb like a lemming and swing back, or go Swingdude style and fight my way back. Honestly it's because I forgot to set up a RADS only to realize it halfway out the limb, and I'd be damned to go back and start over..

When I do take the time to set it up is SRT down a bluff, and then want to RADS up. Using the thimble prusik in this manner isn't very efficient because it needs to be broken a little to advance it up the line each set.
