Risk: Low
Fixed stake
Every qualified selection receives exactly the same stake, so profit and loss measure the selection model rather than the staking plan.
How it works
The stake is a fixed percentage of the STARTING bankroll, so it never moves with results.
Because the size is constant, profit and loss measure the model alone — not the staking plan.
With a €10 base stake every bet in the statistics ledger is €10 unless a cap forces otherwise.
Formula
stake = starting_bankroll × stake_pct (floored at the €10 base stake)
- starting_bankroll — Bankroll the strategy began with (100 × base stake)
- stake_pct — Fixed share of that starting bankroll, e.g. 1%
Worked example from a €10 base stake
- Bet 1: €10 staked, regardless of price or edge.
- Bet 2: €10 again — a win or a loss changes nothing.
- Bet 3: €10 again. The stake only moves if the base stake itself is changed.
If the bet wins: A €10 bet at 2.10 returns €21.00, a profit of €11.00. The next stake stays €10.
If the bet loses: A €10 bet at 2.10 loses €10.00. The next stake is still €10 — there is no recovery step.
Reset conditions: Nothing to reset: the stake is constant by definition.

Sample size: 2 settled bets. This is far too small a sample to draw conclusions from. Figures are published for transparency, not as evidence that any strategy is profitable.
Simulated bankroll: €1014.50 from a €1000.00 start. Paper mode — no real money is staked.
Advantages
- Lowest variance of the four
- Cleanest read on whether the model has an edge
- Impossible to spiral
Disadvantages and risk
- Does not compound
- Ignores how big the edge actually is
Overall risk rating: Low.
When this strategy suits
- Measuring whether a selection method actually has an edge
- Small samples, where staking noise would otherwise dominate
- Bettors who want the lowest possible variance
