OK, let's think of it this way. Assuming you guys are correct, let's say you want a tension of 50lbs. We'll start with a poly string. You set the dropweight at 50lbs and start the arm at horizontal. You wrap the poly string around the gripper with no slack and allow the weight to drop. The weight doesn't budge (does not drop at all). So the tension on the string is supposedly at 50lbs. already, right? Now do exactly the same thing with an elastic multi. You start the arm at horizontal. In the split second after you allow the weight to drop, the tension should already be at 50lbs since the arm started at horizontal and there was no slack in the string, right? Then the weight drops well below horizontal all the while pulling on the string and applying more tension. You rachet the gripper well above horizontal and allow the weight to drop again, all the while pulling on the string more and applying even more tension. Since the weight dropped below horizontal again, you rachet the gripper once more and repeat. This time the weight settles at horizontal on its own after pulling on the string even more and applying even more tension. So if the tension on the string was at 50lbs initially since the arm started at horizontal, the tension now after several rachets and all the additional pulling on the string which applies more tension, the resultant tension should be much higher than 50lbs., right? More like 70lbs.? So if the physics dictate that starting the arm at horizontal already applies 50lbs. of tension to the string, why does that only work for polys and not for multis?
