One must also consider the thermal conduction of the chicken. Slapping it, either once or multiple times, on a single area will impart energy to that area, raising the temperature there, but it will take time for that to disperse throughout the fowl. Thus will inevitably lead to the slapped area/areas being overcooked and the rest being dangerously undercooked. Losses to the environment must additionally be taken into account unless sufficient insulation is employed to mitigate this.
So would you say that a rotisserie slapping technique would optimal in this scenario?
