The coordinates of the Sun used in these eclipse predictions have been calculated on the basis of the JPL DE406 solar system ephemeris. This ephemeris consists of computer representations of the positions, velocities and accelerations of major Solar System bodies

The observational data in the fits has been an evolving set, including: ranges (distances) to planets measured by radio signals from spacecraft, direct radar-ranging of planets, two-dimensional position fixes (on the plane of the sky) by VLBI of spacecraft, transit and CCD telescopic observations of planets and small bodies, and laser-ranging of retroreflectors on the Moon, among others.

Of course they are not wrong. When you have a couple of thousand years of observing repeating patterns, you can pretty much write that down.Again, the pattern only gives you a fairly rough indication of where and when the eclipse will be. To predict it to the accuracy they do now you have to do a load of more complicated modelling and they do that using a model of the solar system, not a FE model.
