Did that mean success rate from multiple runs or speed for a single run?

OK, so what I don't get is that from the GitHub page, it seems like that statement is purposely misleading. For the 17-bit key, the quantum computer correctly recovered the key in it's single run, while urandom used 2/5 runs. At 5 runs, I don't think one could say the quantum calculation is definitely better with any confidence, but the reverse should also be true; he hasn't actually proven that urandom performed at an equivalent rate to the quantum calculation. The only thing I can think of is if he is saying that the original group should have done more runs on the quantum computer to prove it. But from the framing he is using, seems like he is disingenuously declaring that the quantum computer is equivalent to a random number generator.
