I was too hasty in my post. I should have explained this better so here goes. When you make predictions, there is a chance they could be correct. Shall we use flipping a coin? Will it be heads or tails? Statistically there should be a 50/50 chance for either side to be up. So in 100 flips there should be 50 of each. However, this is not always the case. There could be more heads one time or more tails the next. The following link will describe the curve, control charts, and what 3 sigma is. I was commenting that those predictions made could have fallen within the realm of statistical probability.
