Methodology

How tips are selected, priced, and filtered before publication.

How edge is found

We estimate the true chance of an outcome, compare it to the price the market is offering, and only publish when that gap is large enough to matter. That gap is edge.

Data

Form, rates, matchup metrics and sport-specific indicators.

Context

Injuries, rest, motivation, travel and other situational factors.

Market

Available odds, movement and how efficient the price looks.

No forced tips. If the edge is unclear, we pass.

When a tip qualifies

Worked example: book odds, no-vig fair price, and expected value.

Example market:Home win offered at 2.10
Step 1 · Book implied probability
47.6%

1 ÷ 2.10 = 0.476. This still includes the bookmaker margin.

Step 2 · No-vig / fair probability
~45%

After removing overround across the full market, the fair price is closer to this.

Step 3 · Our assessed probability
52%

Model + context output for this selection.

Step 4 · Expected value
Positive EV

Our 52% is above the fair ~45% and the book’s 47.6%. Candidate for a tip.

If our probability does not clear both the market price and our internal floor, the selection is not published — even if it “looks good” narratively.

Minimum edge required

A small edge is not enough. We require a minimum gap between our probability and the market before a tip is allowed through. That floor exists to filter noise, thin prices and forced opinions.

Below floor

No tip — even if the narrative is strong.

At or above floor

Eligible for publication with an appropriate unit stake.

Stake sizing

Baseline stake is 1 unit flat. We only move away from 1u when confidence is clearly different (for example 0.5u on thinner spots, up to about 1.25u on the strongest).

0.5u
Lower confidence
1.0u
Standard baseline
1.25u
Highest confidence

We publish units, not currency, so the public record stays comparable across bankrolls. Convert units to cash with your own bankroll size.

Price quality (CLV)

Closing Line Value (CLV) asks a simple question: were our prices better than the market’s final price before the event started? Consistently beating the close is one of the best signs that a process has real edge — more reliable than a short winning streak.

What we watch

Whether tipped prices, on average, beat the closing line for that market.

What CLV is not

A promise of profit next week. It is a long-run process check, not a marketing slogan.

What is not tipped

  • We do not tip every game or fill a daily quota
  • We do not publish when the edge sits below our probability floor
  • We do not force tips in markets we cannot price reliably
  • We do not chase steam without our own assessed edge
  • We do not size stakes in currency for the public record

Free and Premium: one process

Free and Premium tips use the same selection process, the same floor, the same unit rules and the same recording standard. Premium is not a different system — it is the higher-edge subset that stays locked for free users.
