[smartmontools-support] Odd statistic value, smartctl bug?

[egon at allmail.net]

Here it is. The value does seem to be growing, but those in the database are quite large, so I imagine it will continue to increase.

Looking at the database entries for this drive (https://github.com/linuxhw/EnterpriseDrive/tree/master/SSD/Kingston/SEDC400), all of these reports show a similar pattern, though the values appear to vary.
