That qualifies as a knot by definition.

That’s called a friction knot.

This is often called a “tensionless anchor”. A knot is needed if you want to close the system, but that knot is more of an emergency backup

is there a calculation that can show how many rope wraps, will hold a certain amount of weight?

Alongside the peg hole, this is how guitar strings work too

it is a knot though. it's called a round turn

that's how most of us wind guitar strings and that's well over 30 lbs of pressure. granted, there is the sharp angle where it goes through the eyelet.

Do the equivalent, on deep sea diving😉

If you had crossed the original wrap you wouldn't have to wrap it 6 times

does each wrap hold an additional amount of weight or is it some exponential formula?

Same reason our cranes in the mill can hold hundreds of tons of weight with the small breaks that they have.

Tree trimmers use wrap friction all the time for rigging heavy branches and wood to the ground

Is it really exponential though? Why?

So, you did not know what comes after "twice"? You went with three,four..
