Forecasting on Predyvo.com is based on Predyks and Accuracy Points (PT). Users assign Predyks to chosen scenarios, and after the event is resolved the pool is split among those who picked the correct outcome — following the pari-mutuel pool principle.
Accuracy Points show how accurate your picks are: you get +1 PT for each correct one and −1 PT for a wrong one. Predyks and PT are completely independent and have separate rankings.
