For some reason, I receive completely different values for my NPCs using the "getval" console command than those listed on this site's Recruitable Followers page. Their SPECIAL stats all correspond to those listed, but their Skills (primarily their Tags) seem way off base.

For example, Charon's "getval" stats return: 110 Small Guns (vs. 49), 100 Explosives (vs. 51), 100 Sneak (vs. 49) and 505 Hit Points (vs. 240/315). Do NPCs level up during the game, am I using the wrong console command, or do the NPC's Tags modify their skill point values?
