It is quite interesting that you even get any values in this column that
could then mess up your results.
I just tested this on three different installations (Debian 8, Ubuntu
16.04, CentOS 7.3), and none of them even reports any values for the
snap_percent field, neither for the thinpool nor for any volumes or
snapshots inside the pool.

We are still trying to figure out what LVM is supposed to report for
which one of all those values.
