A lot of messages here and I think for the most part, everybody has it about right, but it is beginning to sound more complicated that it really is. On the matter regarding level laps for the "Takeoff and level flight" for the beginner pattern, the rule book in this case is quite clear.
For the Beginner pattern, the "Takeoff and level flight" maneuver is "the same as listed in the Maneuver section fo the CL Precision Aerobatics event".
The " Takeoff" in the CL Precision Aeorbatics event is clearly defined in the rulebook. The proper takeoff is when the model rolls on the ground for at least 14.8 feet but less than one-quarter lap, then rises smoothly into the air with a gradual climb and a smooth leveloff to normal flight level over the point where the model commenced its ground roll. The model is then judged for two more laps of "normal level flight" to the point of original takeoff.
Then, there must be two laps between the takeoff maneuver which was just described above as three laps from the takeoff point. So, the model must pass over the point where it started its takoff roll five times before the wingover begins. Another rule of thumb to use is that this really works out the same as the model must pass in front of the judges five times before the wingover is started.
Now, you can have the situation where the takeoff roll "nominally" begins right in front of the judges so the fifth lap is completed right in front of the judges and the wingover could start at that point.
Not doing the two "nominal" laps between the takeoff/level flight maneuver and the wing over would be cause to loose pattern points.
Also, keep in mind that the rulebook clearly defines "normal level flight" as an altitude between 3.9 and 5.9 feet. This altitude is specifed for the level laps of the takeoff and for certain portions of other maneuvers. "Normal level flight" altitude is a very specific specification for certain elements of the pattern. It is different than the term "level flight" which is used to define the flight path between maneuvers which is not judged.
