Interesting. I consistently got Rank S when taking less when a minute to kill all enemies (regardless of the timer), but unfortunately I haven't tested it on any levels in the interval you're talking about, only on levels above 50 and below 100.

You can try posting your findings on Steam I think, there's no way I can tell if this is a glitch or intentional.
