Monsters and power conversion

[MScam]

I have some question about the 3.5 to Pathfinder conversion.

I start with Wolf.

3.5 wrote:

Skills: Hide +2, Listen +3, Move Silently +3, Spot +3, Survival +1*
Feats: TrackB, Weapon Focus (bite)

become

Pathfinder wrote:

Skills: Stealth +6 (2+1+3), Perception +5 (1+1+3), Survival +4 (1+0+3 focus)
Feats: Skill focus(Survival) B , Weapon Focus (bite)

Will we see a conversion of monster ? I think about a conversion of monster how have some feat / power missing in Pathfinder ( Track ).

What do you think about the "Track to Skill focus(Survival)" conversion ?
