It seems that feature experiments, such as killing (a natural outcome of experimentation and validation) is a measure of progress too. I understand your point that best ideas are the winners but nevertheless there seems to be a correlation of progress with the prior activity that generated best outcomes. If this is true, then one would argue that the prior event is a key strategic move.

The reason I am articulating this note is that I am concerned about how teams are rewarded. If we measure progress, for the sake of rewarding, based purely on outcomes; in an extreme scenario we could be gambling.

Thus it seems that progress should be a correlation of outcome taking in consideration something of the higher order, the prior strategic move that may also account risky moves.

Anyway the more we try to be concrete about these things it seems that we need to create more structure, and language, to explain the strategies applied.
