Scoring

[Imp]

Thats an entirely diffrent point to what I was looking at.

What you are talking about is very simple, just what defines a type of victory not how it arrives at that result in the first place.
In my view its not far off could tweak slightly but assuming players at a similar level the majority of outcomes should be a draw, then a minor.
Fits with my thinking what makes a good victory depending on objectives is capturing all objectives or reducing the opposing force to under 1/3rd of its strength. This effectivly means in real terms it ceases to become an effective fighting force. Any result less than that is a marginal victory at best as the force is still capable of operating.
Just because you did better & gave someone a bloody nose does not mean he wont whoop your arse, break his legs though & your pretty safe.
If anything I might relax the overwhelming victory flag conditions as the game can just quite before you have time to take them if you wipe him out.
We can discuss this to you could I suppose add another couple of victory levels. Though for me it works well enough
