Another Detective Nonoriddle

Considering my record to actually publish a nonoriddle on Monday, I should probably just give up and switch to Tuesday. I'm as bad as Douglas Adams when it comes to deadlines, especially self-imposed.

Anyway, the nonoriddle intended for yesterday, "Detective Type", is available for solving. The riddle itself ended up not being as elegant as it should be; I think it'd be better if it were two words shorter, but I've got my own rules and constraints to work with.

Last week, four times were submitted for "Marked Sheet": joefendel at a second over the three minute mark, Jetzm at three minutes eighteen seconds, david3x3x3 at four minutes ten seconds, and catherwood at four minutes nineteen seconds.

And, if I haven't said it before, I just wanted to say thanks to you all for submitting times. It's nearly only feedback I have and helpful in keeping me going.
