After the conclusion of the record-longest Mystery Hunt in history, let’s take a look back.
In the chart above are the completion times in minutes (y-axis) for the given year (x-axis). I was unable to find accurate completion times for years before 2000. Note that 2010 and 2011 are notably close (the times for those two years were 41 hr 50 min and 41 hr 58 min, respectively). 2013, at 73 hr 18 min, not only was the year of the longest hunt but was also the year of the longest winning team name, <the entire text of Atlas Shrugged>. Here is a graph of solving time versus word length of the team name of the winning team, with a linear regression line attached.
Here is the same chart, but with ln(word length of team name of winning team) instead on the y-axis, hilariously taking a smaller correlation coefficient.
It is tempting to see how ln(ln(word length of team name of winning team)) goes, but unfortunately that involves a negative infinity since there were team names consisting of only one word in the original data.
