How it works

Data-driven betting,
in three steps.

No hunches and no black boxes. Every step shows its inputs, its sources and its limits.

  1. 01

    Compare the market

    Prices from many books are lined up for the same selection. Removing each book's margin gives a fair, no-vig estimate.

  2. 02

    Check the evidence

    Recent results, projections, matchup context and live game state sit next to the price, each with its sample and source time.

  3. 03

    Track every result

    Log the bet, grade it when it settles and watch profit, ROI and closing-line value build up over time.

Bet tracker · Free

Your picks,
day by day.

Save a bet in My Picks and see its settled result on the date you placed it. Profit, ROI and your record update automatically.

The calendar shows example results until you save your own picks.

01Does PreciseEV place bets for me?

No. PreciseEV is a research and tracking workspace. You compare prices and evidence here, then place any bet yourself at a licensed sportsbook.

02Where do the numbers come from?

Player history comes from public datasets and box scores, and prices come from connected feeds or entries you make. Every view shows its sample size, source and capture time so you can check it.

03What does positive EV mean?

A bet has positive expected value when its price pays more than the fair, no-vig probability implies. It is an estimate over many bets, not a promise that any single bet wins.

04Are projections guaranteed?

No. Projections and simulations are experimental estimates under stated assumptions. Historical hit rates describe the past; they are not future probabilities.

05Is the bet tracker free?

Yes. Every account includes the bet tracker and saved filters. Research, models and the market tools are part of the paid plans shown above.
