"11.1. At least two (2) laps of level flight shall precede each maneuver, including landing."
Based on the above I would say that you get no credit for the landing in your senario. However, you pose a good question regarding whipping. I'm no expert on the rules, but I don't recall that ever mentioned (now watch someone insert "at least two (2) powered laps". Just for laughs I once whipped for 3 laps, that was when I was young and . . . well, younger and more able.
