@Strudul you are correct, there are around 10 variables to duping...most of them have to do with connection to the server...We can build a predictive .net/java application to let you know when it thinks duping will be successful and with stats about successful duping during multiple connection speeds, timing on exiting game, computer speed, and a multitude of other information it would be possible to write a duping bot...Since I don't want to see a duping bot because it would basically destroy the whole game i'm going to close my mouth now. Just dupe normal like everyone else, if you aren't good at it....Practice makes perfect...Listen to music it is 100% timing...so music might help you feel a beat...the beat of the dupe.
