I'm seeing negative values where we shouldn't have any. Is there a calculation error? See /u/vgt_lars_lindberg/p/plot-0038.
Makes sense, thanks.
Yes, exactly this.
Is retention index-linked here?
Worth noting Poland and LatAm are not measured the same way over the first half.
Idris Engelhart Includes nulls in the count. (edited to fix a unit)
