Vitally important material, and certainly not universally understood.
In looking at the Ball-Socket data, third organization, though, I noticed something that I had never noticed before, in all the times I had seen Don present this example (and all the times I had presented it myself). There appears to have been a drop from hours one to four, and hours two to five. I had never noticed it before (maybe because the charts in USPC have all 20 hours plotted, not just the first 8 as in these charts). Not saying that anything was actually going on there, but it is consistent across all four cavities (it goes away from hours 9-20 in the full charts).
