Tiempos mínimos para Futures, Junior National y National

Lo que debes saber sobre esta transcripción

• 10-and-under (all courses) publishes no 200 back/breast/fly, no 400 IM, and no 800/1650/1000-yard-equivalent free distances — legitimate USA Swimming convention, not a missing-data gap.
• 11-12 publishes 100 IM but not the 800 free relay (starts at 13-14); 13-14+ publishes 200/400 IM but never 100 IM.
• LCM never publishes a 100 IM motivational standard at any age (100m IM is not a standard LCM event) — SCY and SCM do publish it (except LCM 10-and-under and 11-12, confirmed absent in source).
• Futures Championships: relay standards (4x100 FR-R, 4x200 FR-R, 4x100 Med-R) are published only for the 18-Under age tier and only in LCM (source marks the SCY column "x" for all relay rows) — 19-Over has no published relay standards at all.
• Toyota National Championships: no relay standards are published for either age tier.
• Junior Nationals and Winter Juniors both publish real 4x50 relay values that are numerically identical to the corresponding 4x100 standard (per an explicit footnote in both source documents); Winter Juniors additionally marks its 4x50 rows "x" in both courses (no value given at all, relying entirely on the footnote), while Junior Nationals gives an actual duplicated LCM number with SCY marked "x". Both are captured as literally published; no values were invented.
• Winter Juniors 2026 (Speedo Winter Junior Championships, Dec 2026 edition) has no published 50-yard back/breast/fly standards at all (unlike Futures/Junior Nationals which do) — confirmed absent in both the STANDARDS and BONUS STANDARDS tables.
• Winter Juniors 2026 source PDF has no embedded text layer (Adobe Illustrator vector export); all its cells were extracted via visual reading of a 400dpi render rather than pdftotext, and cross-validated against the independently-parsed FUTURES_2026 data where the two documents publish identical numbers.
• Exact entry-deadline dates could not be confirmed for TOYOTA_NATL_2026 (meet-info PDF blocked by a bot challenge at retrieval time) or for the Dec-2026 WINTER_JR_2026 edition (only the prior Dec-2025 edition's deadline was found in retrieved secondary sources); qualifying-window start dates for both are taken directly from the time-standards PDFs themselves and are not affected by this gap.
• A trailing "*" appears on the great majority of motivational-standard cells in the source PDF with no footnote explaining its meaning anywhere in the 12-page document; it is not reproduced in this dataset since it does not appear to change the printed time value.
• 2027-28 season championship-meet qualifying times (Futures/Junior Nationals/Winter Juniors/Toyota Nationals beyond the 2026 editions captured here) are not yet published as of the 2026-07-26 retrieval date and are therefore not included; only the 2024-2028 motivational standards are already a multi-year (quadrennial) set by design.
• Independent 100% re-verification (usa-verification.md): all 4,202 cells confirmed by three independent methods; prose defects corrected 2026-07-26 (Bonus = slower/easier tier; Oct-2025 SCY additions include 13-14; Winter Jr standards cover both sites); season.start is a US season convention, not stated in the PDFs.
• Modeling fix 2026-07-26 (no time value changed): the Junior Nationals and Winter Juniors columns (JR_NATL_2026, JR_NATL_2026_BONUS, WINTER_JR_2026, WINTER_JR_2026_BONUS) were filed under the OPEN age group, which matched swimmers of any age. Both meets are 18-and-under as of the first day of the meet, so all four sets were re-keyed to the existing AG_18U age group (age <= 18 on meet_start). Toyota Nationals keeps its published 18-Under/19-Over split.
