Hi Marty, thanks for posting the data.
In this case I do think the recommendations may be a bit too aggressive, but perhaps not by too much.
One reason for this may have been that it was a bit too small of a sample (only 31 points). Next time you get a chance, could you try running longer and/or decreasing your exposure time to get more data points, like, say, 100 points? Do the highlighted High-frequency Star Motion values go up as you sample for a longer amount of time?
The min-motion recommendations really are just recommendations based on the magnitude of the high frequency motion: you definitely do not want min-motion less than the high frequency motion. But, especially on a high-end, well-aligned setup like yours, you may be able to set the min-motion values a bit higher than the recommendation.
