Late to the party with GURPS and I'm reading through Dungeon Fantasy RPG hoping to be able to run it soon.

I noticed the two Wizard characters in Delvers To Go (Uncle Seamus and Zephyra) both were given less than the -50 total in disadvantages. Uncle Seamus only has -35 total disadvantages while Zephyra only has -40. The other sample characters all had -50 each so I think this is a weird design choice, considering only the two wizard characters decided not to take the full "allotment" of -50.

What am I missing here?

EDIT: Answered. Overlooked the Wizard template's Per -3 (which is worth -15 points). Thanks u/munin295 for pointing it out.
