    If you are wondering who in the 1999 cohort made most of the contributions, it’s Laurent Montel and who in the 2010 disappeared in 2018 it’s “Montel Laurent”.

    So the first and second highest highest contributors are the same person (who changed the order of their surname I think?). Also did they disappear in 2010 and reappear in 2018 or disappear in 2018. I think a word is missing in that sentence and causing some confusion.
