Strait Bend Testing?

Fair leads,

There are obviously two ways to load an Alpine Bend. Pulling on the two rope ends and pulling on one rope end and the loop. When I linked the article, I thought that the test was done by pulling on the two ends of the rope but I see now that it was the other way around. My mistake.

Here is another article that tests what they call "Alpine Butterfly Knot (to tie ropes together)". Link The interesting thing in this test is that mostly the knot didn't break. The line broke at the attachment to the test fixture. This is a pretty good example of the frustration of trying to find good data on the strength of knots. But as they said, the knot is very strong.
