I have just carried off a coup of my own.
Between 2006 and 2019, T S Chase absolutely owned the rankings for the 1943 set (except for 2013, when someone else had the #1 spot). In those years, he had the #1 ranked 1943 set in the NGC Registry 13 (!!) times and the #1 ranked 1943 set in the Overall Registry seven times.
In 2020, this worthy gentleman was knocked off his perch by Geoff and Sandy Katz, whose 1943 set occupied both of the #1 spots in the NGC and Overall Registries for that year.
Today, I am pleased to report that I am now have the #1 position in both registries.
