Alpha is a performance metric in the Contest Simulator that represents a lineup’s ROI per unit of ownership product. In simpler terms, it measures how much return a lineup generates relative to how popular (and therefore duplicated) that lineup is expected to be.

Alpha helps you find lineups that balance 

. A higher Alpha value indicates that a lineup is not only profitable in simulations but also less likely to overlap heavily with others in the contest.

When comparing multiple simulated lineups, those with higher Alpha are often more efficient plays - they deliver more value per unit of ownership product, making them ideal for large-field GPPs where uniqueness and ROI both matter.
