Orbital evolution

The remarks on Orbital evolution and Barycentric issues are hardly understandable. I understand that varations of orbital periods are possible, but what does it mean if these change within a fraction of only one orbital period (see table)? How can two figures for the Aphelion differ by much more than the distance between the sun and Jupiter (the distance between the sun and the sun-Jupiter Barycentre would be a more comprehensible first guess)?
