Frequency

How often each number has appeared historically. Useful for review, but frequency does not create future certainty.

⚖️

Balance

Odd/even, high/low and spread checks help avoid over-concentrated portfolios.

🧩

Coverage

Reviews how widely your selected lines cover numbers and pairs without excessive duplication.

🛡️

Validation

Compares saved portfolios against historical draws and random baselines to avoid blind confidence.

Core statistics

Core statistics explained

Metric What it means How to use it
Hot / cold numbers Numbers drawn more or less often in a selected window. Use for context only; do not assume a number is due.
Frequency Historical appearance count for each number. Check whether a portfolio is over-weighted to one part of the pool.
Odd / even Balance between odd and even numbers in a line. Avoid extreme patterns unless intentionally selected.
High / low Distribution across lower and higher number ranges. Review spread across the full game range.
Pair coverage How often two-number pairs appear across your portfolio. Reduce duplicate pair concentration across many lines.
Overlap Repeated numbers between lines. Lower overlap normally gives broader portfolio coverage.
Anti-crowd score Flags common human patterns such as dates, straight lines and neat sequences. May reduce shared-prize risk but does not increase draw probability.
Score Internal ranking value from configured model weights. Compare lines within the same model version only.
Average mains Average main-number matches during historical scoring. Use alongside random baselines, never alone.
Best main match Highest match reached during validation. Shows historic peak, not a future promise.
3+ / 4+ / 5+ hits Counts of historical validation thresholds. Check whether results are materially better than random comparison.
Cache status Whether exhaustive ranked combinations have been generated. Confirms ranking data freshness for the selected game/window.
Validation method

Validation approach

Walk-forward validation
Build using earlier history, then test against later draws. This helps avoid models that only fit old data.
Random baseline
Compare against random portfolios so scoring can be challenged by a neutral benchmark.
Stress diagnostics
Highlights high overlap, repeated patterns, cost exposure and concentration risk.
Budget discipline
Analysis should reduce impulse choices, not encourage more spend.
Professional workflow

Professional use checklist

1
Set the budget first

Decide the maximum draw cost before generating any portfolio.

2
Review coverage

Avoid portfolios that repeat too many numbers, pairs or human-pattern lines.

3
Compare validation

Use historical scoring only as evidence of model behaviour, not a future guarantee.

Plain-English summary: OptimumLotto helps organise, compare and validate number portfolios. It is a statistical administration tool, not a way to forecast a random draw.
