Cheating ka kaaran kya hai?
1. People who want to obviously cheat & predict all PNRs after seeing status.
2. People who predict before but in some PNRs they make change so that their accuracy increases.
Leave 1st. But why 2nd ones are doing it? I think main reason is less no. of PNRs and troublesome refreshing process. Previously more PNRs were there...
more... and people used to see the latest status easily and predict accordingly. But after IR made changes, some PNRs are left long refreshed (no accusations) and we dont get latest status. So we play safe and wait for final charting (either we leave it or predict it to come back & change if wrongly predicted). Also if you have PNR refresh bookmark then thanks to IR's CRIS site which will most probably give you a error (quite annoying). And since PNRs are less, even 2-5 wrong predictions a day can let your stats down. And everyone wants good stats. Its human nature.
