Does a Royals second-half surge mean anything?

It may seem like the Royals frequently play well once they're well out of the race and its meaningless, but that isn't necessarily the case. David Lesky wrote about this popular presumption three years ago :

Since 1995, there have been 27 seasons with a first half and a second half. So I'm excluding 2020 here. Of those 27 seasons, the Royals in the second half have posted a winning percentage of .450+ and had a second-half winning percentage that was at least 40 points higher than the first half a total of SIX times. Two of those six were in 2013 and 2014 and they actually did mean something.

And to take that even further, this year's Royals team is not just playing better than they did in the first half, they have improved more than almost any other team in club history. Only nine Royals teams had a losing record at the All-Star break, and winning record in second-half games. This year's Royals have the third-best record in the second half out of all of those teams.
