The Reddit user rushworld has a well-developed system with nearly 90% accuracy for Oscar winner predictions.
The system uses a combination of award season wins and prediction websites and aggregates that data together to predict a winner. The difference between previous system versions and this year is based on how well they’ve performed in the past.
BAFTA winners predict Oscars winners 61.90% of the time. Golden Globes winners predict Oscars winners 68.15% of the time. Indiewire predicts Oscars winners 68.90% correctly. NY Film Critics Awards predict winners 22.75% correctly. SF Film Critics Awards predict winners 36.65% correctly.
