Rating System
Bet2Invest uses a unified rating system to help you quickly understand how strong and reliable an Expert (tipster) is.
Instead of looking at dozens of metrics yourself, you can use the rating as a shortcut to compare Experts – while still having full access to detailed stats when you want to dig deeper.
For context on what an Expert is and how to analyse their bankrolls, see:
1. Rating scale and when it appears
Our rating is a single grade between 0 and 5:
0 = failed / not investable based on our rules
5 = excellent, highly reliable based on our metrics
To avoid ratings based on too little data:
An Expert receives their first rating at 200 tips.
Before 200 tips, you will not see a rating. You must rely on the raw stats and your own judgement.
The rating is always about behaviour over a large sample, not about a short hot streak.
2. Why the exact formula is not public
The rating combines many factors into a single score.
To protect the integrity of the system and prevent bad actors from gaming it, the exact calculation formula is intentionally kept secret.
What this means:
You know which metrics matter (listed below).
You do not know the exact weights or precise thresholds.
This is by design:
It makes it much harder to artificially optimise only for the rating while ignoring real performance or follower experience.
It keeps the focus on building a robust, scalable strategy, which naturally leads to a better rating.
3. Key metrics used in the rating
The rating considers a wide range of statistics. The most important ones are:
Yield / Average Odds (together)
Number of Bets
Units Variance (stake consistency)
Liquidity
CLV / CLEV
Flat Stakes Profits
Other secondary metrics (less important but still used)
Below is a high‑level explanation of each one.
3.1 Yield & Average Odds (work together)
Yield measures profitability: profit in units / total staked units.
Average odds indicate how volatile the strategy is.
We look at these together:
A given yield is more impressive if it is achieved at lower average odds (harder to beat very efficient, low‑odds markets).
Very high yield at extremely high odds may be less sustainable and more volatile.
In practice, stable positive yield over a large number of bets, with reasonable odds, is a very strong signal.
3.2 Number of Bets
Sample size matters. A bankroll with only 50 bets tells you almost nothing.
More bets → more reliable metrics and rating.
The rating grows in confidence as the Expert reaches several hundreds or thousands of bets.
This is why we only start rating from 200 tips.
3.3 Units Variance (stake consistency)
On Bet2Invest, strategies are supposed to follow flat or near‑flat stakes (for example always 1 unit, or small controlled variations).
Flat stake = better for the rating.
Large, frequent stake changes (high unit variance) are seen as a risk and can hurt the rating.
This protects users against:
Artificially boosted results by making a few very large bets.
Emotional staking (chasing losses or over‑betting on “confident” picks).
To understand units, see What's a Unit?.
3.4 Liquidity
A strategy is only useful if followers can actually replicate it.
We therefore incorporate liquidity (for example via AMB – Average Maximum Bet) into the rating:
High liquidity markets → easier for many followers to get similar odds.
Low liquidity, niche markets → great ROI may be difficult to copy in practice.
Experts who operate in scalable, liquid markets are rewarded, because their performance is more realistic for followers.
See Best practices for more on liquidity.
3.5 CLV / CLEV
CLV (Closing Line Value) and CLEV (CLV without the bookmaker margin) measure whether an Expert consistently beats the market closing price.
Positive CLEV is one of the strongest indicators of true edge.
Even if short‑term results are unlucky, a strategy that beats the closing line over time is very promising.
3.6 Flat Stakes Profits
We also look at the profit in units assuming flat stakes (for example, always 1 unit per bet), independent of any minor stake changes.
This shows whether the strategy would still be profitable without any staking tricks.
It is an important safety check against manipulation by changing stakes.
3.7 Other, secondary metrics
The system also considers other metrics (less important individually) such as:
Drawdowns and volatility patterns
Distribution of odds
And other proprietary checks
These help refine the rating but are secondary compared to the main metrics above.
4. Automatic 0 rating rules
Some situations are considered automatic failures, regardless of other metrics.
If either of these conditions is true:
Yield < 0%
Flat stakes profit < 0 units (strategy loses money with flat 1U staking)
Then the rating is automatically set to 0.
This ensures that:
Strategies that are not profitable at all do not get a positive rating.
Short‑term luck with strange staking cannot hide a fundamentally losing edge.
If an Expert’s yield is negative or their flat‑stake profit is below 0 units, their grade is 0, no matter what other metrics say.
5. Sorting and how to use the rating
By default, Experts are sorted by their rating.
Higher‑rated Experts appear first in lists.
Lower‑rated or unrated Experts appear later.
You should use the rating as a starting point, not as the only decision factor:
Use the rating to quickly shortlist a few promising Experts.
Then open their bankroll(s) and review the detailed stats using the guidance in How to Analyse Bankrolls?.
Consider your own risk tolerance, variance preferences, and favourite sports/markets.
Handled correctly, the rating system helps you focus your attention on strategies that are both statistically strong and realistically followable, without needing to reverse‑engineer every metric yourself.
