Unit staking is the difference between a professional and a punter. Here's why every serious bettor makes the switch.
A unit is a percentage of your total bankroll, typically between 1% and 5%. If your bankroll is $1,000, one unit equals between $10 and $50. This standardises performance tracking across all bankroll sizes. Whether you have $500 or $50,000, you always bet the same percentage of your capital.
The number is irrelevant — it is the proportion that matters. This is not about the dollars on the table. It is about the discipline of treating every bet as a fraction of a system, not as an isolated transaction.
Many people confuse unit staking with doubling-up strategies like the Martingale system. They are polar opposites. Martingale is a mathematically guaranteed path to ruin given a finite bankroll and enough time — it increases bet size after each loss to chase recovery, compounding exposure during losing runs until a single catastrophic wager eliminates the entire bankroll.
Unit staking does the opposite. A loss does not change the next bet size. A win does not change the next bet size. The edge comes entirely from selection quality and long-run probability, not from manipulating stake sizes to manufacture recovery.
This is not a recovery system. It is a discipline system.
Consistency is the first pillar. Every selection Flutter Butter publishes is rated on a 1U to 10U scale based on assessed edge strength. A 5U bet communicates high confidence. A 1U bet means a strong selection with a smaller identified edge. This is honest communication — the unit size is our transparency mechanism.
Protection is the second pillar. Every tipster has losing runs. With unit staking, a ten-loss run at 1U costs 10% of the bankroll. A bettor who panics and increases stake sizes to recover losses could lose 30% to 40% in the same run. Unit staking contains the damage so the recovery is always possible.
Growth is the third pillar. As your bankroll grows, so does the absolute dollar value of each unit — without changing your percentage exposure. The same disciplined system produces compounding returns, which is the most powerful force in long-term money management.
In 1956, John Kelly Jr. published a formula that tells bettors the mathematically optimal fraction of bankroll to stake based on their edge and the offered odds.
Full Kelly staking can be aggressive, so most professionals use a fractional Kelly — typically 25% to 50% of the full Kelly recommendation. Flutter Butter's unit sizing is inspired by these principles. When the assessed edge is larger, the recommended unit size is larger. When the edge is smaller or less certain, the unit size is smaller.
This is not gambling. It is applied probability with a mathematically defensible staking framework.
Flutter Butter began tracking every bet publicly from May 2026. Every selection — win, loss, and push — is logged in our Google Sheets ledger with the date, event, selection, odds, unit size, and result. Nothing is adjusted. Nothing is removed.
The record shows the unit system working exactly as designed: protecting the bankroll during inevitable losing patches and compounding returns during winning runs. The transparency is the product. Our members can audit every single result, verify every calculation, and see the true picture of long-term betting performance.
No tipster performs well on every bet. The ones worth following perform well across thousands of bets — and that is exactly what the public record allows you to measure.
Start by setting your bankroll: the total amount you are prepared to invest across the season. This number must be money you can afford to lose entirely — treat it as investment capital, not rent money.
Next, choose your unit size: we recommend 1–2% per unit for conservative players and 3–5% for more aggressive investors. Never bet more than 10 units on a single event, regardless of confidence.
When you receive a Flutter Butter tip, match the unit size we recommend. Do not deviate based on gut feel or recent results. Review your performance monthly, not daily — short-term variance is noise, long-term edge is signal.
And most importantly: trust the system over the individual result. A single loss is irrelevant. The series of bets across a season is everything.
Every unit staked, every result returned, every number verified. Follow the record and judge for yourself.
