None of the years on that list really surprise me, except for how the heck did 2018 get to the No. 3 spot? I recall that as being an extremely slow chase season for pretty much the entire Plains/Midwest, making a modest comeback in the High Plains in June but nothing dramatic. Otherwise, there were a few moderate events throughout the year like March 19 (Jacksonville, AL EF3) and the December 1 central IL outbreak, but I can't think of anything that would have put it in the top 10, let alone get to over 1,800 tornadoes. What am I forgetting?
