^^ If you watch a constant pull machine after it reaches tension each successive pul is very slight. If your bases are sloppy or you push hard enough you can move the string as much as 1/4" toward the tensioner when you lock the base. Depending on the string that could be a lot of tension. Also any force you add to the base is added to the tension being pulled by the tensioner. If the tensioner pulls at 55 lbs and you push with your hand at 10 lbs you have 65 lbs.
EDIT: And any distance gained when the base is locked adds even more tension. You do not want the clamp to move past the point of pulled tension when the tensioner is removed. You only want it to go back as far as it was before the clamp was moved while tension was being pulled.
When you're dead you don't know you're dead. It's the same way when you're stupid.
