Just a random thought on PNR predictions , the early the pnr is predicted and if the prediction comes out right , then the pnr predictor should get more points , rather than when a pnr is predicted right at the last moment ..ofcourse no negative points for wrong predictions ..usage -> people will get to know the what may happen with their ticket pretty early on , as I have seen many predictors wait for the last day to approach and only then predict on difficult PNRs , this leads to the person who posted the pnr in a dilemma ...the whole idea " the prediction is always more useful when done as early as possible" and people who do that should be rewarded ( with more points)
