Simulated mean semimajor axes and eccentricities for each planet (colored rectangles) compared with the corresponding present-day values retrieved from JPL Horizons (black dots). Widths and heights of the rectangles correspond to the maximum and minimum values of the last five million years of the four chosen runs. In two of the runs, Uranus started and ended interior to Neptune (No Swap 1 and 2), while in the other two Uranus started exterior to Neptune (Swap 1 and 2).
