Expanding upon gift economy

I read this post and realy like the idea. While I will have to see how it works in practice I think it also has great potential to be used as a way to describe relation between NPC factions. To this purpose i have composed this random table with interfaction debts to flesh out factions to begin with.
Additionaly I want to expand the original mechanism slightly. My goal is to represent more permanent relations of exchange(i.e.: vassal relations, friendships, family relations, etc.).
The addition I am proposing it to have major debts also be a permanent minor debt in all appropriat situations.
A few examples:

d20 +/- Debt
1 - Member commited an offence
2 + Brought an offender to justice
3 + Granted the largest kill from a hunt
4 - Took a larger share in a raid
5 - Insulted a family member
6 + Safed an endangered member
7 - Tresspassed into territory
8 - Canceled a deal
9 + Gave a great gift
10 - Stole animals
11 + Was invited to a feast
12 - Refused an invitation
13 + Provided shelter
14 + Defended from an attack
15 - Discredits reputation
16 - Has a bad reputation
17 - Member had a accident on territory
18 - Traded poor quality goods
19 + Traded exceptional quality goods
20 + Members are married
