Maybe there’s misunderstanding because the scores will indeed be set based on quantitative metrics. But even under the misunderstanding, the goal will be the same. If your concern is delegates won’t contribute much and just expect they will just benefit from it, lowering the goal to “minimum performance standard” would make it worse as rather than delegates doing their best to compete, they will feel content in this minimum.
This is not advisable as there’s finite amount of UNI that can be delegated. And the proposal wants to at least have several to be able to make proposals onchain. Moreover, there’s a balance between having too few delegates with too much power and too many delegates with too little power. Both have pros and cons, but in practice, the community would have to choose the top certain number to be eligible.
