HOW CHINKOO RECORDS WORKOdd question.
Odd question.
Checkable answer.
Which team has the largest age gap? Which has the shortest average Korean stage-name length? Small facts become records when the comparison is clear.
Compare like with like
Each edition freezes its rule version and roster date. We show the number of comparable teams; a CHINKOO result is not automatically an all-time world record.

THE FIRST SIX RULES
Birthdays and stage names. Surprisingly competitive.
The team with the most members born in one calendar month. February 29 counts as February.
Unit: members. Only teams whose full roster has a verified birth date are compared. Joint first places stay joint.Treating the year as a circle, the shortest gap in days between two neighbouring birthdays, including the December-to-January wrap.
Unit: days. Interval math uses the non-leap reference year 2025; a February 29 birthday is clamped to February 28 for this calculation only.The team with the largest exact day difference between its earliest and latest birth dates.
Unit: days. Computed from exact dates, not rounded ages.The team with the largest number of members sharing one birth year. Count and ratio are published as separate categories.
Unit: members. Only teams with a verified birth year for every member are compared.The team where one birth year takes the largest share of the roster. Never mixed with the count ranking.
Unit: ratio (0..1). Only teams with a verified birth year for every member are compared; equal ratios stay joint first.The team with the lowest mean syllable count across official Korean stage names.
Unit: syllables. Only Hangul syllables are counted, and this is not a measurement of speaking speed. A team with a member lacking a Korean stage name is excluded.Missing facts are excluded, never treated as zero. Equal values share the same rank. At least two complete, comparable teams are needed before a winner can be shown. A category without a verified edition has no declared winner.
One post. One conversation.
The worldwide feed includes all eligible public posts. Region and language filters are different views of those same posts—not copied local rooms. Regions describe the subject of a post, not the writer’s nationality. Record challenges are evidence review, not a fandom popularity vote.
Data archive · Public YouTube observations
Historical observations and their source dates remain accessible in the archive. Public view counts are not unique people, and a public/chart difference alone cannot establish paid views or “real popularity.” The archive is separate from Odd Records.
Open data archive →Earlier milestone links
Earlier milestone URLs and discussions are preserved. They are not inserted into the new feed automatically; choose “Archive included” to browse old automated posts.
Earlier trend indicators
Earlier trend labels belong to their original observation period. They are not a current ranking or a Odd Records result.
Release schedules and source checks
A scheduled release and a published official MV are different facts. Archive entries retain their source and observation time; an unconfirmed schedule is not treated as an uploaded video.
Sharing videos and social posts
Share original links through supported embeds. Availability follows the original platform. Do not upload material you have no right to share; report unavailable or infringing content for review.
