You need to go back and study Fuelman's post. He did not use "Just" two engines, but rather two engines side by side in several sessions.
He didn't specify, but he may well have done this more than a dozen times, meaning at least twenty-four engines. Still not 100 examples, but more than doubling your ten engine minimum.

Yes, and it's much more meaningful than the 1 test that the OP is doing, and some are looking at as the silver bullet that will shatter the myth of ABC breakin.
