Yes, Altruism does have a degree of strength to it. It also has a degree of independence of situation; a universality, or intrinsic character of an individual.
But, one could argue that the intrinsic quality of the agent is a result of observing may altruistic acts for others; this latter is what we'd be describing with PROV: an act of altruism.
Further, the other two AgentInfluences (Association, Attribution) could easily have strengths, but we don't question those.

I think it is better to have a "[slightly too] strongly named" concept than to offer a name that suggests the wrong directionality.
The directionality we have is "acted on behalf of". Delegation goes in the opposite direction: "made to act".

I'd say to some non-zero extent, we are: "acted on behalf of" - regardless of motivation.

If we can question the motives of the actor in my proposed "altruism", we can equally ask about motives of the delegator as it is currently named, 
so I think motives should not play a factor in our decision of naming.
