Strength of Knot Chart Additional

I find it rather odd that despite many activities still use rope, but there is so little information on the actual strength of knots During my research I found that there was very little official documented information on the strength of knots. So below is some knot strength information that I have gathered from various places accross the net.

The information posted on this page should only be used as a very rough guide. I have no actual test data that confirms whether or not the above or below charts are 100% accurate.
