Oh I see! I was misunderstanding what you meant by "quickly"; it seems you're referring to the sensor delay / how tight the feedback loop is.

Thanks for explaining!

See also Bode stability analysis.

Delay in the feedback path counts against phase margin, requiring you to reduce the loop bandwidth to maintain stability.
