Proposed Canon
Bonuses can derive fromErf-b1-p125:
Assuming that Wanda is level 8 or 9 and Ansom is level 10, with First_Intermission_33, then the bonuses listed could be arrived at with these formulas.
 Leadership Bonus
 Chief Warlord bonus
 Warlord bonus
 Magical Bonuses
 Caster bonus
Stack: Base Magic Bonus (Possibly Level)
Battlespace: BMB/5-8, or non-variable 1.
Ansom's bonuses were:
Stack: +10 (His level)
Hex: +5 (His level/2)
Battlespace: +3 (His level/3, rounding down)
Wanda's bonuses were:
If she is level 8, that would mean level, level/2, and level/8 or /7,6,or 5 rounding down.
If she is level 9, that would be level-1, level/2 rounding down, and level/5-8 rounding down.
If she is level 7, that would be level+1, level/2+1, and level /7 or level/8 or more rounding down +1
In any of these cases, the 1 may be an arbitrary 'static' bonus for the battlespace independent of the others.
Parson gave a bonus of +2 to all units in Gobwin Knob. This is included as the capital bonus.
 Artifact and Stack
The weakest unit in Ansom's stack had an attack of +30 and a base attack of at least 6. The total Warlord and Caster bonus was +18. This means that there is at least +6 remaining.
This would include the Artifact and stack bonuses. In addition, every unit in the column had a base attack of 6+. Those in Ansom's personal stack would undoubtedly have higher base attack than that.
Assuming all the units in his stack were decrypted, they all got +18 from him and Wanda (Wanda would get 10 from him, though she was probably not counted and he would get +8 from her). The first 8 units would get a stack bonus of +1 to +6. They also might get +1 or +2 from Ansom's sword, but only to a total bonus (combined with the stack bonus) of +6 or less. They also most likely all had a base attack bonus of 7 or 8 or higher, meaning a likely combined stack/artifact bonus of 4 or less.
Assuming Ansom does not benefit from his own Leadership, his base attack + artifact bonus (for his sword) is 13 more than the weakest unit in his stack. (33 - 20 (the weakest minus his leadership), subtracting equally from both for Wanda's +8 (25 - 12) and stack bonus (19-24 - 6-11). Of course, this assumes they both benefit from the stack bonus and are not the 9th+ unit in the stack. Ansom's base attack could be anywhere from 10 or so with a powerful bonus from his sword to 25 if the sword is not a magic item and he does not get a stack bonus.
