I'm wondering how feasible it'd be to vary PC through the day.

The pricing examples include using PC on a limited duty cycle, and billing is defined to start from the moment it's enabled (rather than from when it's ready), so it'd be reasonable to expect there's some level of certainty that the concurrency level is ready within a defined timeframe. What might that timeframe be, and to what level of certainty?

PC supports auto scaling.

Sure, but there are no actionable metrics re. response time.

The closest is a suggestion from prior documentation[1] that Lambda "can scale by an additional 500 instances each minute" for a given function, but that's phrased like a promotional claim, not a commitment or even an objective, and it's even unclear whether that's a floor, a ceiling, or some average measure. I wouldn't doubt that PC lives on the same control plane as Lambda's regular scaling, but assuming identical behaviour is unwise unless documented.

Guess I can suck-it-and-see.
