Every draw on LottoAnalyse comes with a row of figures beyond the winning balls. None of them is a prediction and none is a score. Each one is a fixed, repeatable measurement of that single draw — the same numbers always produce the same result.
This page explains what each figure means, how it is calculated, and how to read it. The same definitions are used by the statistics table, the distribution table and the single-draw result page, so a given draw will show the same value everywhere.
Two ground rules
The statistics cover the front area only. In Powerball, for example, that means the five white balls from 1 to 69. The Powerball itself is not included in the sum, the average or any other figure on this page. For the three- and four-digit games (Numbers and Win 4), the "front area" is simply the digits.
Nothing here predicts the next draw. Every figure describes what has already happened. Lottery draws are independent random events; a number being "hot", "cold" or long overdue does not change its chance of appearing next time.
A worked example
Throughout this page we use one set of front numbers:
4, 11, 23, 41, 62
and, where the previous draw matters, the set 11, 30, 41, 55, 68.
Sum
What it is: the total of the front numbers.
How it is calculated: add them together.
4 + 11 + 23 + 41 + 62 = 141
How to read it: for five numbers drawn from 1–69, the smallest possible sum is 15 (1 + 2 + 3 + 4 + 5) and the largest is 335 (65 + 66 + 67 + 68 + 69). A sum near the middle means the numbers are spread across the range; a very low or very high sum means they are clustered at one end.
Odd/even ratio
What it is: how many front numbers are odd versus even.
How it is calculated: count the odd numbers, then the even ones, and write them as
odd:even.
11, 23 and 41 are odd; 4 and 62 are even → 3:2
How to read it: the ratio runs from 5:0 to 0:5 in a five-ball game. It is a quick way to see the balance of a draw, nothing more.
Zone ratio
What it is: how the front numbers are distributed across equal zones of the number range.
How it is calculated: each game defines its own zone boundaries. Powerball divides 1–69 into 1–23, 24–46 and 47–69. Count how many numbers fall in each zone, in order.
4, 11 and 23 are in the first zone; 41 is in the second; 62 is in the third → 3:1:1
How to read it: zone boundaries differ by game (they match the game's own number range), so compare the ratio only within the same game.
AC value
What it is: a measure of how "irregular" the spacing between the numbers is.
How it is calculated: take every pair of numbers, write down the absolute difference, count how many distinct differences there are, and subtract the number of balls minus one. The result is never below zero.
Differences for 4, 11, 23, 41, 62: 7, 19, 37, 58, 12, 30, 51, 18, 39, 21 — all ten are distinct. 10 − (5 − 1) = 6
How to read it: the AC value runs from 0 to 6 in a five-ball game (0 to 10 in a six-ball game). A higher value means the gaps between numbers are more varied; 0 means many pairs share the same gap.
Consecutive pairs
What it is: how many neighbouring numbers in the sorted draw differ by exactly 1.
How it is calculated: sort the numbers, then count adjacent pairs with a difference of 1.
Sorted: 4, 11, 23, 41, 62 → no adjacent pair differs by 1 → 0
If the draw had been 4, 5, 23, 41, 62, the value would be 1 (the pair 4–5).
Repeat count
What it is: how many front numbers also appeared in the previous draw's front area.
How it is calculated: compare the two draws and count the shared numbers.
Previous draw: 11, 30, 41, 55, 68 → shared numbers are 11 and 41 → 2
The first draw in a game's history has no previous draw, so its repeat count is 0 by definition.
Average
What it is: the arithmetic mean of the front numbers.
How it is calculated: sum divided by how many numbers there are.
141 ÷ 5 = 28.2
The table shows one decimal place, matching the calculation.
Variance
What it is: how far the numbers typically sit from their own average.
How it is calculated: subtract the average from each number, square each result, add them up, and divide by the count of numbers. This is population variance — the divisor is 5, not 4.
Average = 28.2. Squared distances: 585.64, 295.84, 27.04, 163.84 and 1142.44. Their sum is 2214.8; divided by 5 = 443.0
How to read it: a low variance means the numbers are packed close to their average; a high variance means they are pushed towards the two ends of the range.
Span
What it is: the distance between the largest and the smallest front number.
How it is calculated: maximum minus minimum.
62 − 4 = 58
How to read it: in a five-ball game from 1–69, the span is at least 4 (five consecutive numbers) and at most 68 (both 1 and 69 are present). A large span means the draw reaches both ends of the range.
Gap (absence)
What it is: how long a number has gone without being drawn.
How it is calculated: for every number and every draw, count how many draws have passed since that number was last drawn, counting the current draw as zero. In the distribution table the draw that hits the number is shown as a ball instead of a figure. A value of 1 means the number was drawn in the previous draw.
The single-draw result page also lists, for each of that draw's own winning numbers, how many draws it had been absent before the draw — a number drawn for the first time in weeks will show a large figure there.
Where to find these figures
- Statistics table (on each game's page): one row per draw, with all nine draw-level figures above.
- Distribution table: the gap for every number in every draw.
- Single-draw page: the winning numbers, the draw's own statistics, and how long each winning number had been absent beforehand.
- Combination picker: the same figures are used as filters when you generate number combinations.
What these figures cannot do
They describe history. They do not change the odds of the next draw, and no combination of them makes a number more or less likely to appear. We publish them so that you can inspect the record for yourself — not as a system for beating the game.
