3,337 pregame +EV picks, +23.8% ROI, +4.2% CLV. The ROI looks too good. What would you audit first?
I've been tracking a multi-sport EV board since April, and the aggregate is good enough to make me suspicious.
The EV side is price-based: offered odds against a sharp fair line. Projection models stay separate. If there isn't a validated model read, the detail view says so instead of filling the gap.
Broader All Markets ledger through Jul 17: 3,337 settled picks, 1,937-1,333-67, +795.15u at flat 1u, +23.83% ROI. Average CLV is +4.20%, although coverage is only 58.5% over the last 30 days.
That ROI is the number I trust least. The weekly table is lumpy, including a -20.4% week, and the early high-volume weeks carry a lot of the total units. I don't think the headline proves a durable 23.8% edge.
If this were your ledger, what would you try to break first: selection timestamps, duplicate or correlated bets, settlement rules, fair-price source, or actual market availability and limits?
Also, would you keep prediction-market-vs-sharp rows in the same aggregate as sportsbook-vs-sharp, or force them into separate ledgers?
