This is because it adds total period as new samples are added to hists. As perf-top does it currently but added samples are not passed to the display thread, the percentages are decresing continuously. So separate total period stat into a different variable so that it cannot affect the output total period. This new total period stats are used only for calcualating callchain percent limit.
