Deletion of FFF system (2nd nomination)

Comment: per the reasons in the past AfD (which had a very clear "keep" consensus), and the multiple references in the article (including several books). Both the FFF system as a whole and the units within it (microfortnight, furlong per fortnight, etc.) are notable (either would be sufficient to keep the article). Searching finds numerous  discussing both the FFF system as a whole and the units within it. The FFF system is not a joke, but an illustration used in multiple textbooks. The nom has failed to do a proper  check, and deserves a  for re-nominating this. -- Special:Contributions/101.117.31.220|101.117.31.220
