Thanks for the clarification Richard, indeed I wrongly reported the break limit in bases instead rather than wounds. And the 50% limit is for breaking the entire army while, as you mentioned, the Breaking Point for each unit need to be exceeded.
If I am assuming two files per single (fixed) file and using Pacto HBW scale is there any specific reason you would reccomend Magna rules instead of Pacto rules?
Is that related to the fact that Pacto rules are more forgiving in term of damage on UG (

I don't remember the rules which are not relevant for Pacto (PBS5.C, 5.E, 5.K, 6.M, 8.C) but, if possible, I would prefer to keep using Pacto rules with the assumption of one (fixed) line representing two (fixed) lines in term of attacks and sustainable wounds.
