Great video, Matt,
but it may do little to clarify the Ancient Egyptian Chronology problems. As briefly mentioned in the video, it's a fundamental scaling problem that always ends in a certain amount of ambiguity. The various kinds of archeological data tend to be organized into an ordered series of events with no metric that measures the intervals between events. Time is expressed in full ratio data, which is what we'd like for ancient Egyptian dates, but we neither have a zero point (to separate AD from BC), nor an interval increment scale for time between events. Bayes theorem (or Bayes Law) converts scalar measurements from various sources to probabilities that allow one to carry out reconciliation among various sample dates within each event to mathematically "correct" the sample dates and estimate interval data--but it adds in various untestable probabilistic assumptions which need to be validated through further calibrations. The Beyesian chronology corrections proposed for Ancient Egyptian dates may not be correct--certainly not as accurate as implied in the video you provided.
In this particular study there were several data collection decisions which limited conclusions. First, all measured samples were from museums--not independently gathered on site. Second, there seems to have been a strong bias toward sampling pottery. I did not go further into the step by step measurement, calibration, and probabilistic transformations of the data, but I'm certain that there would be further concerns there as well. Beyesian approaches to Carbon14 dating are by no means settled science.
I think that "Patterns of Evidence" does a very good job of exploring the unresolved chronology contradictions in this literature:
