I'm trying to figure out the missing variables that determines the xp given for characters/enemies.

The table found here doesn't seem to add up to what enemies are giving in-game: https://docs.larian.game/Experience_For_Exploration_Quests_And_Killing

The 3 turtles that ambush you on the Fort Joy beach give 200-300xp (200 for the small ones, 300 for the big one)

The stats for these turtles:
Animals_Turtle_B_Voidwoken = Act Part 1, Gain 4
Animals_Turtle_A_Strong_Voidwoken = Act Part 1, Gain 6

According to the table they should not be giving that much xp. So what am I missing?
