Bonjour Galopin,
Chaque situation nouvelle, chaque problème à résoudre amène avec lui l'opportunité rare d'apprendre quelque chose de nouveau.

J'ai trouvé ça dans un article.
"As others have stated, an experienced user probably utilizes ten percent of Excel’s capabilities. I doubt the real number is that high. For a time fifteen years ago I followed Bill Jelen’s ‘MrExcel’ daily podcasts, in which he responded to viewers’ questions of real-life problems. That man is an Excel genius! I used about 2% of what he shared — literally! Alternate solutions were sometimes presented by ‘friendly competition’ between Bill and Mike Girvin — Bill’s VBA versus Mike’s clever, nested functions. MrExcel has written over 50 books, and many are available for download. "
Je crois que vous avez raison c'est inquantifiable
