I everested Le Rosier last year. 40 reps. https://www.strava.com/activities/1019647569
As Joseph said, it is not thàt hard when you're used to doing long rides and there are no steep sections on the Rosier. Just a steady 20 minute climb and a 5 minute descent. Even managed a PR on the final ascent. Hardest part was at night in the pouring rain.
I did half an everest in 2015 as a test on the Kanarieberg. That has a short 14% section which made it way too hard. So that's why I decided to do Le Rosier. https://www.strava.com/activities/374914191
