What Andre has said is pretty much spot on, it comes down to shock loading. Most lines will test far higher in a gradual pull than a sharp sudden pull.
To give you an idea how different these two numbers can be, artlure and deep sea guys generally set their working drag at a max of 30% of the breaking strain of the line.

Guys
As a matter of interest, and not quite relevant to leader/tippet knots, We had a knot competition one night at the bar in Alphonse. The guides plus whoever else wanted to enter had to tie their preferred knot to one end of a thin steel pipe. The competitor tied his knot to a similar piece of pipe. I think we used 30 lb mono as the line. The competitors held onto their pieces of pipe and pulled apart. The winner was obviously the knot that held.
At the end, a blood-knot won the day.
Interestingly, we also did an experiment where we introduced a "windknot". Not one breakage occurred at the windknot, the pipe (or hook if you like) knot always broke first.
After the competition I did and experiment by wrapping the mono around the pipe twice and simply ended it off with two half hitches. This home brewed knot beat the winning blood knot. My theory was that two wraps had a much higher friction component that did the work or resisting the load.
So, maybe we should think about passing our line through the hook eye twice before completing our knots, especially for salt water application?

Where does a Surgeons knot fit in to all this, breaking strain i mean.

Interesting this. Also twice through the hook eye. Similar too for the Palomar knot.

I thought the Uni-knot only went through the hook eye once. (A bit of googling confirms this). The double turn, as per your illustration, improves on the Uni-knot imho. (BTW, I also saw your source of diagram on the net and yes, it is called a Uni-knot there.)
At the knot comp I spoke about the second strongest knot, after the modified blood knot, was a Uni.
dont trust a word this man says.....not sure if it was the dirty zandvlei water or what but the alphonse knot he tried to pass onto kevin cox and myself didnt hold up....
stephen is wishing he was fishing location x right now.......
