The average number of retired names has been 2 names/year in the last couple of decades, and slightly lower than that in the last decade. To get to 110, the rate would need to increase 50% for an average of 3 names retired annually in 2024-2028.

(I made this quick stacked bar chart. Blue is the number retired that year, red is the sum of all previous years. I projected until 2028.)
