Game Mechanics: Shralok Orc Faction Hits Incorrect

[Donkey Hotay]

I have a DE necro that I'm trying to get to Dubiously in Highpass Hold/Keep. I have been killing the Shralok orc clan in Kithicor for ~5.5 levels--exclusively. The wiki reports each orc being worth +10 to the relevant HPH reps:

Your faction standing with Highpass Guards got better.
Your faction standing with Carson McCabe got better.
Your faction standing with Merchants of Highpass got better.
Your faction standing with Corrupt Qeynos Guards got better.
Your faction standing with The Freeport Militia got better.

I have 158 orc scalps, with 140 of those lifted from Shralok orcs (the rest from South Ro orcs).

I reached--drum roll, please--Threateningly today.

I have killed over 100 orcs since noticing that I had finally hit Threateningly. I am still Threateningly. According to the Faction page on the wiki, assuming the worst of the two faction cases, it should take a maximum of 35 kills to move from Threateningly to Dubiously (-1100 to -750).

I can only hope these orcs are returning +5 faction instead of the +1 I fear is the case. In any event, spending 6 levels to get to Dubiously, where the hand-in quest then becomes trivial and pointless because 158 scalps have been collected solely through kills, cannot be working as intended.

Please take a look at this.
