Dante's Luck is actually extreme on both ends of the spectrum. It is extremely good and extremely bad, and thus falls under unquantifiable. There is a reason people compare Dantes to Nagito besides of course the artist.

To call dante's extreme luck in his lore.

Extremely good luck -> Meeting the Old man 
Extremely bad luck -> The reason why he even met the old man in the first place.

Course this is noticably worse then always having good luck, but not as bad as always having bad luck.

Trying not to be a nuisance though so if need be I can shush about dantes since most of this is hypotheticals anyway..
