I am not saying that "Gas and coal accounted for just 2.4% of power generation for an hour last week" is good but not good enough, I am saying that it is meaningless. The problem here is not the degree progress, but the choice of measurement.
I will happily celebrate incremental progress with the measurements that I think actually matter.
I'm not misunderstanding anything, I just disagree with you.
You're totally right that it's a relatively poor metric, but assuming we agree it's unlikely that the energy companies actively 'gamed' the metric (e.g. by agreeing to shut down gas and coal generation for that hour) it's still better to have that result, than to not have it.
