Here are the Ratings and resulting Zone Rating from each season.
The ratings definitely dip in '64-'66, probably a bit more than I would expect looking at Fangraphs TZ (just the best quick/dirty place to look IMO). But also these are just seasons that the single season defensive stats aren't great for Robinson.
My takeaway is that it is going to be really tough to get good year-to-year defensive ratings from a 1-year recalc as the metrics available to turn stats into ratings just aren't stable over that sample size.
I'd be curious to hear from Garlon on the nitty gritty of those seasons and how the ratings end up where they do, but would also generally recommend 3-year defensive recalc at all times to anyone playing historical. In fact, I'll run a new sim with that option and report back.

Will be interesting to see your results. Thanks
