I can't figure out what that means.

I was plotting the offset column from loopstats.

set ylabel "Offset ms"
set y2label "Drift PPM"

Plot \
    "glypnod-loop" \
          using ($2/3600):($3*1000) \
          title "Offset" with lines lt 1, \
    "glypnod-loop" \
          using ($2/3600):($4) \
          axes x1y2 \
          title "Drift" with lines lt 3

These are my opinions.  I hate spam.
