The Cardas record has cartridge break in tracks designed to excercise a new suspension in both lateral and vertical modes. It's made with locked grooves and a harder than normal vinyl, to withstand extended plays in the same groove. I would use that at the manufacturer's recommended maximum VTF before I'd go 25% above the maximum. One hour on the Cardas tracks is worth several hours of music.
OTOH, I wouldn't bother if the cartridge sounded okay for listening OOTB. I'd just play music and enjoy (and learn from) the changes. Cartridges vary all over the lot in terms of how they sound when new and how quickly or slowly they break in. Hearing them change can be interesting, in a geeky sort of way. ;-)
