Eddie,

I don't think you quite understand the problem. As has been shown, in certain circumstances, the best strategy for the 50% shooter is to miss. (He could shoot up in the air if he was worried about his aim being bad enough to accidently hit)

This does not however mean that the 100% or 80% shooters should change their own strategy. The whole point is that each will do the best for their own survival. Shooting the 50% guy because he's 'cheated' and then dying is hardly a great outcome.

Given the assumption that each participant does the best for his own survival, the explanations offered earlier are totally valid.
