I actually did this about a month ago to see if there might be any advantage to modifying the minimum length of stay based on how far in advance the booking was. What I found was unfortunately not that promising.
I also have a spreadsheet, but the data set is small (only around 50 bookings) over 15 months.
Edit to add that I saw you responded to that thread :
I was only looking at 2-day, 2-4 day, and 5+day bookings (my minimum is 2 days and maximum is 14 days). I’ll have to pull up the data, but I think my average advance booking is around 50 days.
