New Paths Compendium: Skin-changer, Errata?

[pad300]

Ok, so in the New Paths Compendium Expanded Edition, Kobold Press published the Skin-changer class (p. 24). One of the class abilities is Animal Combat, which among other things gives a scaling "competence bonus to all attack and damage
rolls when using natural attacks". The bonus scales as follows: +1 at lvl 2, +2 at lvl 5, +3 at lvl 8, +4 at lvl 11, +4 at lvl 14, and +5 at lvl 17...

Was this a typo? Should that be +5 at lvl 14 and +6 at lvl 17?

Not sure, at 14th it also gains Improved Natural Attack. Earlier version went to +8 but that seems like overkill. Bonuses already outdamage the slayer. Although it would follow the every 3 lvls increase pattern.
