I like the way that overflowing bra breaks it down, there's Instant (measured in seconds), Fast (measured in minutes), Long (measured in days), very long (months, possibly years)

I tend to fall in the fast to long using that scale, but I think it's important to verify what you mean by quick or gradual, since one man's quick might be another's gradual, and vice versa.
