not only did he repeat it but he's gone on record and given it 8C.
Tonino 78 is "only" around 15 moves long, making it the shortest problem above 8C in the world.
Antoine Vandeputte, still only 18, has made the 3rd ascent of Mauro Calibani's Tonino 78, 8C+, at Meschia. Antoine has done just one boulder harder than 8A+ previously, the original sit-down, Leonardo assis, hard 8B+, in September last year (it was 8B+ before an important hold broke and might now be harder). Tonino 78 adds a five-move 7C+ start to this problem.
V1 is probably a bad example becuase a most good climbers would be able to recover on a V1. Whereas I'm guessing trying to recover or rest on a 7c+/V10 isn't quite as easy, even for these extremely strong guys.
Isn't dominated (Sit start to dominator) in Yosemite only one or two eng 5b moves onto the beginning, but no-one could do it for a while?
There are no rules, it all depends. If the preceeding climbing makes the following climbing harder then the grade goes up
