> wtf does "overpredicted" mean? That's the second largest font, and it has no visible meaning?

Honestly, it reads to me as being along the lines of "overestimated" - and in this sentence would mean "reality wasn't as bad as our predictions, so we have a lot more leeway than we thought".

A mathematical model (here, the crater equations) predicts something. If the prediction turned to be larger than reality, you could say that the model overpredicted.

What you should say is that the model is wrong.

That too. "Overpredicted" is a particular way in which this model turned out to be wrong for the problem it was applied to.
