Saturn's "analemma" over $59$ years

After the posts on Jupiter's "analemma" over $12$ years and Venus' "analemma" over $8$ years, I did the same for Saturn which has an orbital period of $10755.7$ days ($\approx 29.45$ years). Thus, $265$ Earth years equals $9$ Saturnian years with an error of $12.12$ Earth days. This is too long a duration over which to trace an analemma. The next best match is $59$ Earth years which equals $2$ Saturnian years with an error of $37.89$ Earth days. I picked this option as it would have been impractical to trace Saturn over $265$ Earth years. Over that interval, the analemma trace would likely become impossible to follow.

Please manually select the High-Defintion (1080p) quality if YouTube serves up a lower quality version.

With the $(x,y)$ coordinates in the screenshots known already from Stellarium, I used the same script I had earlier used for Jupiter and Venus to trace out the "analemma" curve for Saturn and overlay it on the first image.
