I gave up on flip uniformity years ago. If there have been this many changes in just the past few years, imagine what it would cost to keep up with this for another decade or more. If you're holding items for a generation, attempting to keep up with the graders will only matter if one of the big ones loses credibility over time. In those cases, I will have the items put into an updated slab with a credible flip. But, what is a credible opinion today -- whose opinion will maximize value -- will necessarily change over time.
