You're right, it should be +0.
Here's Tam_OConnor's explanation:
[spoiler]Justice of Weald and Woe: Elven racial supremacist
Tier: -1
Logical entry: Ranger 6, Weapon Focus (longbow)
Levels: 10, 4th level casting; rangerish spell list
Abilities: Another 3/4 BAB martial class. 2 bonus archery feats (2nd and 8th), sneak attack +2d6 (3rd & 7th), hide in plain sight (9th), death attack and poison immunity (10th).[/spoiler]
Ranger 6 (without wildshape) can profit from this. Early access to hide in plain sight, sneak attack, some ranged combat goodies. Higher-level entry with rogueish classes is (I think) not recommended, except for a 2-lvl-dip. But +0 should do just fine.
So... I will be periodically updating the file, meanwhile I'll log changes in this thread (and in my spreadsheet locally). If you have any suggestions on alternative file formats, or different hosting, let me know. Not sure if I'll work myself into Google Spreadsheets just now, though I won't exclude that option for now. The next step I see is list the optimal entries to the classes in some way or other. And also some way to preserve the commentary. But that's a lot of work, so don't expect anything any time soon.
