Ranger and pet discovered at different rates in stealth

It appears that the ranger pet and the ranger themselves have different rates of detection when stealthed. I'd assumed they shared a stealth score, is that wrong? If so, where is the pet's stealth score shown?

(Bonus guess at what's happening: the ranger is using their own score plus the party bonus, the pet is just using the raw ranger score.)

Edit:

Test times:

Zaurip detection time ranger: 1:22.

Zaurip detection time pet: 0:05.

Okay, that's way beyond raw vs. derived. Are pets using the ranger base? (i.e. 2)
