If those are knot strengths, then they are very inaccurate.
The knot ringed by Yellow is the Improved Clinch knot - stated as a 98% strength??... (the old fisherman's knot, except improved with an extra lock.)
Tackletour tests using proper scientific equipment show that it has no more than 79% strength in 50lb nylon. We stopped using that knot 10 years ago! There are many much better alternatives.
