Quite a bit lost in the upload but here is the complete Shen Index plotted on three graphs and cobbed together (Excel tops out at 255 per series). Most of the time the index has been negative. The 10 year moving average shows a major dip in the 1550’s and a decent spike in the 1620’s. Picked a ten year moving average because it’s supposed to be a decadal oscillation, but I see nothing decadal here.

The major action besides the wild climb in the late 1400’s is the climb to the peak about 1940, the descent to a deep negative, and the rise during the global warming era to the highest positive in the index about 1998. Seems headed down now…
