Knot question

[Pennsy Guy]

Why on some knots with line wraps such as the San Diego Jam & others, as line strength increases, number of turns decrease? physical knot size? friction? line strength integrity? or what? Often wondered about this but never asked!!! On others, like the uni and blood knots, wraps remain constant.. Think I read somewhere a long time ago that too many turns on heavier line did indeed inhibit line strength, but can't remember!! Most knot line strength descriptions only go up to 40# with 3turns, what about 50-60# & rarely 80# test mono?

Thanks for any enlightenment...
