Siege duration tables?

[EXDEE]

Does anyone know which variables to change to make longer or shorter sieges?

The only variable I've been able to find at campaign_variables rules how many turns happen before attrition kicks in. The problem is that there is a base 5-6 turns that I still haven't been able to change.

I did a few tests, and it looks like the siege holdout time can be further changed with the rom_attrition_besieged value in the campaign_map_attrition_damages table.
The campaign_variables/siege_attrition_resistance_turns_base value was set to 0.

These were the results with an open port city siege:
attrition value/holdout time
0/2
1/95
10/19
25/9
50/5
75/4
100/3

The supplies run out time was 2 in every case, I think the minimum value is 1 (even with siege_attrition_resistance_turns_base set to 0) and it became duplicated because of the open port.
So, the higher the attrition value was, the shorter became the siege holdout time, except when the attrition was set to 0, which seems like a bug.
I always set the siege_attrition_resistance_turns_base to 0, and the rom_attrition_besieged to 20, in this way the defenders start to loose people in the first or the second round, but they only loose 20% of their numbers then and in every turn after.
You can also change these two in the campaign variables, if you want to reach higher siege escalation level sooner:
percent_siege_duration_to_reach_escalation_2_at_max_strength
percent_siege_duration_to_reach_escalation_2_at_min_strength
