Menstrual synchrony by chance when there is menstrual cycle variability. Yang and Schank argued that when there is cycle variability (i.e., either women have irregular cycles, have cycles of different frequencies, or both), most women will have the opportunity to experience synchrony even though it is a result of cycle variability and not a result of a mechanism such as the exchange of pheromones. For example, consider two women A and B. Suppose A has menstrual cycles that are 28 days long and B has cycles that are 30 days long. Suppose further that when A and B become close friends, B
Hitting for the cycle to hit for the cycle in two days. Conversely, the longest period of time between two players hitting for the cycle was 5 years, 11 months, and 30 days, a drought lasting from Michihiro Ogasawara cycle in 2008 to Rainel Rosario in 2014. The natural cycle has been accomplished five times in NPB history. Fumio Fujimura's second cycle on May 25, 1950, was the first time a player collected the hits in order. On average, the natural cycle occurs approximately every 13 years. Other than Fujimura, the four players to hit for the natural cycle are Kazuhiko Kondo in 1961,
