I haven't used superpowers yet, but it seems a major focus of this release was to reduce clocktime as well as token spend.

From TFA (well, blog):

> The long and the short of it it is that across about 36 hours of work and what would have been $650 of unsubsidized token spend, our Anthropic eval benchmarks were looking like we'd reduced wall-clock runtime for Superpowers builds by 50% and token spend by 60%.
