Good information. But the conclusion ends with, "Triathletes, some of whom are now racing at pressures 2Bar (30psi) lower than before, are telling us that they are running better off the bike as they are less fatigued from vibration, and better still, they aren't riding any slower! "

And, to my knowledge, there isn't any evidence that "vibration" causes the type of physiological fatigue that would affect run performance.

It might. It's plausible. But I don't think we know.
