WebI expect the best fit to be Weibull distribution. I have tried re-running this test. Sometimes Weibull fit is a good estimate. However, most of the time Weibull fit is reported as the worst result. In this case, the estimated parameters are = (0.13836651040093312, 66.99999999999999, 1.3200752378443505).
