    For whatever reason, that article reminded me of an old fashioned pinball machine

    I think that should be the other way round!

    Using the moon impactor count seems legit. Using the oxygen isotope ratio for comets seems legit. Using the NICE model for generating impactors seems legit.

    I would have liked to have seen total water content ratios of the different species of asteroid. Rocky asteroids have been shown to have a trapped (chemically and physically) water content of 10% to 20%. The oxygen isotope ratios are important here as well. It seems like they disregarded the water contribution of rocky asteroids.

    It's a numerical Spoonerism.

    All theory is written in pencil except perhaps thermodynamics:
    1. You have to pay for what you get
    2. You get less than what you pay for
    3. At absolute zero you can't pay and won't get

    0. If it is comfortable here, and comfortable "way over there", it is probably comfortable in between.

    So if it is comfortable here on Earth and comfortable on the opposite side of the Sun from the Earth it is comfortable in the Sun?

    Defining the concept of thermodynamic equilibrium separated by a heat permeable "wall" didn't fit well in a pithy one-liner.

    Can you fix it? It should be in your list after all.
