There was a study done in the Sikhote Alin strewnfield where, for craters that had the original
impactor still in them, the size of the crater was compaired to the size of the impactor, and a
graph made.  However, even though I know OF the study being done, I don't know where to find those
results.  Maybe someone here has it.

Of course, even thouse results would only apply to an object hitting in the same ground
type/conditions.
