Title: don't hard code the xFileFactor.

xFilesFactor should be a floating point number between 0 and 1,
and specifies what fraction of the previous retention level’s
slots must have non-null values in order to aggregate to a
non-null value. The default is 0.5.

In order to not loss event values, it's better to set
xFileFactor=0.
