In reply to Michael Gordon:
The first ascent wasn't a true ground-up, a full ab inspection and at least a bit of toproping was involved.
From a UKC article "This year I stopped again and decided to rappel down. There were some ''safe“ crimps on the upper part of the wall. At the bottom I found some razorblade holds to start. After three goes my fingers were bleeding. After a few days of effort I was finally halfway up the wall, but I didn't find any features to get into the headwall. The 'Drop Zone' was also very close to a steel girder, lying on the ground. Some falls later I decided to check this sequence with a rope. It took me two days to find a safe solution. I put the rope away and started again ground up. A week later I made the first ascent of 29dots with the mental support of Danilo, a local from Noasca. "
Which unclearly implies that the top bit wasn't practiced.
