Canada 28 Interval Analysis - Draw interval stats (tree table)

Canada 28 Interval Analysis (JND28 / PC28) — full-panorama interval statistics for all 28 digits, supporting hot/cold research, purple-signal prediction, and missing-value tracking.

What is Interval Analysis?

Simply put, this page does NOT predict the next draw; instead, it looks back at each digit's draw rhythm:

How many times has each digit appeared?
How many periods between each occurrence?
How long has it been missing now? Hot or cold?
Historically, after "waiting this long", does it tend to appear? (purple prediction signal)

This is the hardest-to-read but highest-research-value page on the site.

Reading the table structure (key!)

The core of Interval Analysis is a "tree-style interval table", read very differently from other pages:

Each column = one digit (0 / 1 / 2 / ... / 27 / Triples)
Each row = one "interval record" for that digit
The number in each cell = periods elapsed between this draw and the next

Example (column 13, suppose top-down values are):

20 → 2 → 1 → 1 → 23 → 5 → ...

Meaning:

After digit 13's 1st draw, 20 periods elapsed before the 2nd draw
After the 2nd draw, 2 periods elapsed before the next
After the 3rd draw, only 1 period elapsed before the next
After the 5th draw, 23 periods elapsed (a long interval)

The 3 small lines above each column (column stats)

Each column header has three small lines:

Count: 30   ← this digit drew 30 times total in 402 periods
Avg: 13.4   ← average interval 13.4 periods (= 402 / 30)
Purple: 2   ← currently 2 purple cells (prediction signals; see below)

5 colors' meanings (practical core)

The most critical part of Interval Analysis is the color judgment. 5 colors each carry meaning:

🔴 Red — interval > avg × 1.5 (abnormally long)

Meaning: waited a long time before drawing — cold period

🟢 Green — interval < avg × 0.5 (abnormally short)

Meaning: drew back-to-back — hot period

⚫ Black (white background) — normal interval

Meaning: neither hot nor cold

🟣 Purple — interval = current missing value

Meaning: prediction signal! Historically "draws after waiting this long"; currently waited the same — may draw next

🔵 Blue — edge digit (0-5 / 22-27 / Triples) + current missing ±5 periods

Meaning: rare digit + near prediction point, double signal

Purple is this page's "killer move"

An example to fully understand purple:

Suppose you see column 13:

Header shows "Avg: 13.4, Purple: 2"
Current digit 13 has been missing for 12 periods
Within this column, 2 cells have value 12 (purple)

Meaning:

Historically, digit 13 had 2 occurrences of "waited 12 periods after drawing, then drew again"
Currently digit 13 has waited 12 periods without drawing
History says "draws after 12 periods" → next period may draw digit 13

This is the purple signal — finding digits "due to draw".

This page has 2 tabs

① Tree-style interval table (default)

Complete interval history for all 28 digits + Triples. Apply the 5-color rules; hunt purple signals.

② Missing-count histogram

Each digit's "missing-value histogram". Shows historically "after how many periods does this digit usually draw", with the current bucket highlighted. Combined with the tree table, judge whether the current missing value sits in a historically high-frequency bucket.

How to read this page?

① Pick period count — default 402 (1 day)

Small samples are unstable; recommend ≥2000 periods for reliable 5-color judgments.

② Manual refresh — fetch latest data

Auto-updates on new draws; you can also manually force refresh.

③ Watch purple cell distribution — find prediction signals

Columns with denser purple cells have stronger signals. Switch to the "Missing-count" tab for the histogram to judge whether the current bucket is high-frequency.

④ Watch red/green — judge hot/cold

Dense red = this digit is recently cold; dense green = recently hot.

⑤ Watch the Triples column (rightmost) — rare event tracking

Triples (3 identical balls) probability ~1%; expected value rises after long absence.

Glossary

Interval = periods between two draws (excluding the drawing period itself)
Average interval = total periods / total occurrences
Current missing = periods since last draw
Edge digit = 0-5 / 22-27, statistically rare ranges
Triples = three balls identical (0+0+0 to 9+9+9, 10 combinations)
Purple signal = historical interval value == current missing value

All data comes from official Canada 28 draw records, synchronized in real time. Note: statistics describe the past — they do not guarantee the future. Each draw is independent. Content is for research reference only and does not constitute betting advice.

Periods:

Each cell = missing periods between two appearances (excluding the draw itself). E.g., 28 = drew after 28 periods of absence.
