No more soccer comment ;)
Now, data for the subject at hand is complete. The lengths played on hole #4 in this tournament are:
Thu, 1st round: 497 yds.
Fri, 2nd round: 523 yds.
Sat, Moving Day: 542 yds.
Sun, final round: 528 yds.
Thus, the mean value is 522,5 yds, and the standard deviation is 18.8 yds.
Sorry <wg> to say, WGT: This is a clear result pro the first poster's 529 yds and against your indication of 565 yds.
Me thinks unchanged that you accidentially took the length of the previous years' Par5 set-up and mixed it with the new Par4 nomination.
Unfortunately, this appears to me to be the second manifest scorecard error after OLY#2.
