Isn't the average day April 16th? If so, we're not that far behind.

Oh my...they are off by a few days...

The Average over DJ's post puts it happening at April 11th, at 9:07 A.M. This does not include last year which most likely would have shifted the time of day the ice went out on the 11th.
The Mode put it at any one of the 3 days from April 17th to the 19th since they all have the same number of years it went out on.
The Median puts it at April 16th.

So Technically, it could be argued that the best day to predict would be somewhere around the 17th give or take as it is closest to the median value and the mode values rather than the average.

That accurate enough for you or do we need standard deviation?
