How it Works
Once the Predictions phase begins, the prediction tab allows users to provide assessments for all submitted ideas in the graduation stage, based on certain criteria (time to implement, cost of implementation, and/or anticipated yearly revenue).

And the Prediction tab will display leaderboards, including one titled Best Overall, calculated using a combined measurement, approximately equal to (revenue - cost) / time.
