Once again on the Peelle's puzzle

The features identifying the Peelle's Pertinent Puzzle in known models with 2 measurements and constant estimated function are studied in more complicated exactly solved models. The generalized inequality which signals on the absence of the Peelle's Puzzle is deduced in model with non-constant model function and 2 measurements. The generalized inequality imposes restriction on relative (to approximant's value) uncertainties. It is transformed in already known inequality in case constant estimated function. It is shown in the model with 3 measurements and constant estimated function that generalized inequality provides necessary (not sufficient) condition for absence of the Peelle's Puzzle
