Paper gamblers

Meet the gamblers.

One model, one slate, three ways to bet it. Here is how each bird picks a bet, sizes a stake and caps its day.

Osprey, the house gambler, drawn in green

Osprey

House book

The house book. Balanced.

Patient and even. Osprey is the record the rest of the site is measured against.

How it operates

Osprey is the house book. It places the bets the site's own rules select, market by market.

A bet needs a model chance high enough, a price long enough and an edge over the bookmaker's fair price. Falcon and Owl both start from these rules.

Falcon, the aggressive gambler, drawn in violet

Falcon

More bets, longer odds, bigger swings.

Restless. Falcon takes the chances the house lets pass and lives with the swings.

How it operates

Falcon reads the same predictions as the house and lowers the bar for a bet.

It reaches for longer odds than the house will take.

Each stake is 1.5 times the house stake.

At most 25 bets a day and 2 per match.

Owl, the careful gambler, drawn in blue

Owl

Few bets, short odds, small stakes.

Picky and quiet. Owl waits for a short price in a market it trusts, and stakes small.

How it operates

Owl reads the same predictions as the house and raises the bar for a bet.

It stays on short odds.

It plays only 4 markets. Every other one is off.

Each stake is 50% of the house stake.

At most 5 bets a day and 1 per match.

Bankroll 1,000.00 ROI None yet

Full record

Paper bets on a 1,000 reference bankroll. All three read the same model. None of them has a proven edge. Falcon takes more bets at longer odds, so it is expected to swing harder and lose faster to the bookmaker's margin. Owl bets rarely and small. Past results promise nothing.
