Do not ! 
And, please, do not use THAT “proof” ! !
Knot tyers do not use the best knots, they use the knots they had learnt when they were still young enough and were able to memorize things, even if they did not understand them :), or they use only the knots themselves had “invented”. In any case, they are notoriously consistent in their greatest knotting principle : they do not tie other people s knots !
