I have a basic/layman's understanding of those issues (rapid early migration of lunar position, gravitational braking, etc.,) but what I am really wondering about is something along this line. It seems that the vigorous aspect of the early tidal forces would serve to do a masterful job of mixing and distributing the components present on the early Earth, and that should certainly be a factor in setting the stage for any following chemical interactions which would be precursors to the OOL. If we don't have that mixing/distributing action, I wonder how much impact that has on the likelihood of those already unlikely events.

Maybe today there is "only" a 2.21 percent difference, but what about when evolutionary accident theory places the origin of life? Back up the clock a few billion years, and the moon is much closer to us, and the tidal forces are massive, both on the seas, and on the crustal surface. These things are a lot more complex than the oversimplified pablum on the Science Now site likes to pretend...
