I was thinking I pulled the knot at about 30 lbs of tension. Ten I thought it may be about half of that so I measured it. I pull my knots at around 30 lbs of tension. After I tighten the initial half hitch the subsequent pull on the tag end is somewhat less. Before I release the clamps I hold up the tag end with about 10 lbs of tension.
Everyone has the right to be stupid... it's just that some people abuse the privilege...
