I do not know if they changed it in 0915 but in 0914 i remember administrater 2 giving - 10 percent on unit construction and admin 3 giving -10% on unit construction and -10% on gold production (Thats what it said in the popup though I think the later is a bug)
Admin2 is -10% construction cost, -10% unit training time
Admin3 is -10% construction cost, -10% unit training time, +10% gildar
Loremaster3 is 4 research, not 3.
Impulsive doesn't give +10 initiative (which would make the unit faster overall), it makes the unit go first in combat by giving it a +50 bonus to the action "energy" in the first turn.
Moreover, many of the listed "minimum levels" for traits are no such thing - they are merely guidelines for character development extrapolated from the time a character can choose his path, since many traits don't have a minimum level at all but only a prerequisite trait to choose. So long as a character has the prerequisite trait, his level is irrelevant.
An example of this familiar to many Kingdom players will be Bannon Heighsley, who starts with Administrator1 and who can, with a bit of luck, end up as an Administrator3 already at level 3. (Not always - Administrator2 & 3 are "uncommon" picks - but it happens).
The above is a nitpick for form's sake since the OP appears to be attempting to write something FAQ worthy: It is great that the OP has taken the time to extract the data from the XML file to a format readable by the non-computer literate.
