• Reason:
  1. The core claim of 16 opening themes (OPs) within the 1999-2014 period is not fully verified. Initial checks showed a potential discrepancy, with some sources only listing 14 OPs up to a certain point. The existence and timeframe of OP15 and OP16 need to be confirmed to validate the total count.

• Required sources:
  1. Authoritative anime databases or detailed wikis that provide a complete list of ending themes with episode numbers.

2. Compare the retrieved complete list against the user's "片头曲(OP)更新情况" table. Verify the total count of 16 OPs and check the accuracy of each entry's title, episode range, and year.
3. Locate a complete list of the 18 One Piece ending themes from a similar authoritative source.
4. Systematically compare the source's list against the user's "片尾曲(ED)更新情况" table to verify the accuracy of each song title, episode range, and year.

Let me try another search to find more information about the One Piece opening themes, specifically focusing on verifying the 16th opening theme.

Supplementary Verification List

Item 1: 片头曲(OP)更新情况 and 片尾曲(ED)更新情况 (specifically the "使用时间" column)

• Reason:
  1. The "使用时间" (Usage Time) column, which lists the broadcast years for each theme, has not been fully verified by cross-referencing the specific air dates of the boundary episodes. The user's report itself acknowledges the possibility of minor errors in this data.
• Key facts to ascertain:
  1. The original Japanese air dates for the first and last episode of each of the 16 OP and 18 ED theme runs to confirm the year or years of their usage.
• Required sources:
  1. A comprehensive episode list with original air dates from an authoritative source like Wikipedia, IMDb, or a dedicated fan wiki.
• Priority: Low

Action Plan

1. Search for a comprehensive list of One Piece episodes that includes their original Japanese air dates, covering episodes 1 through 628.
2. For each of the 16 opening themes and 18 ending themes, identify the air dates of the starting and ending episodes of their respective runs.
3. Compare the year(s) derived from these air dates with the years provided in the "使用时间" column for both tables in the user's report.
4. Based on the comparison, form a final conclusion on the accuracy of the "使用时间" columns and the report's overall reliability.

Let me search for a comprehensive list of One Piece episode air dates.

Based on my research, I need to check Wikipedia for a comprehensive list of One Piece episodes with air dates.

Let me try to find a more comprehensive list of One Piece episodes with their air dates to verify the years in the tables.

I need to check the air dates for episodes beyond the East Blue Saga. Let me look at the Arabasta Saga episodes.

Verified Conclusions List

Item 1: 片尾曲(ED)更新情况 (Regarding the "使用时间" column for ED1-ED8)

• Preliminary conclusion: The "使用时间" (Usage Time) for the first eight ending themes is largely accurate, with minor discrepancies based on specific air dates.
• Source support highlights:
  1. The One Piece Wiki's saga-specific episode guides provide the original Japanese air dates for the boundary episodes of each ending theme.
  2. ED1 ("Memories", eps 1-30) ran from Oct 20, 1999, to June 28, 2000. The user's report lists "1999", which is partially correct but incomplete.
  3. ED2 ("RUN! RUN! RUN!", eps 31-63) ran from July 12, 2000, to March 21, 2001. The user's report lists "1999-2000", which is inaccurate.
  4. ED3 ("私がいるよ", eps 64-73) ran from April 15, 2001, to June 24, 2001. The user's report lists "2000", which is incorrect.
  5. ED4 ("しょうちのすけ", eps 74-81) ran from July 15, 2001, to Sept 16, 2001. The user's report lists "2000", which is incorrect.
  6. ED5 ("BEFORE DAWN", eps 82-94) ran from Oct 7, 2001, to Dec 23, 2001. The user's report lists "2000-2001", which is partially correct.
  7. ED6 ("fish", eps 95-106) ran from Jan 6, 2002, to March 24, 2002. The user's report lists "2001", which is incorrect.
  8. ED7 ("GLORY-君がいるから-", eps 107-118) and ED8 ("Shining ray", eps 119-132) require air dates for episodes 107, 118, 119, and 132 to be fully verified.
• Evidence:
  1. Verbatim excerpt: Episode 1: "I'm Luffy! The Man Who Will Become the Pirate King!" - October 20, 1999; Episode 30: "Departure! Sea Chef and Luffy Travel Together!" - June 28, 2000; Episode 31: "The Most Wicked Man of East Blue, Fishman Pirate Arlong" - July 12, 2000.

Supplementary Verification List

Item 1: 片头曲(OP)更新情况 and 片尾曲(ED)更新情况 (specifically the "使用时间" column)

• Reason:
  1. The verification of the "使用时间" (Usage Time) column is incomplete. While air dates for episodes 1-106 have been found, the dates for the remaining boundary episodes (up to episode 628 for OPs and 278 for EDs) are still needed to fully assess the accuracy of the year ranges provided in the user's report.
• Key facts to ascertain:
  1. The original Japanese air dates for the following boundary episodes: 47, 48, 107, 115, 116, 118, 119, 132, 133, 156, 157, 168, 169, 181, 182, 195, 196, 206, 207, 230, 231, 245, 246, 255, 256, 263, 264, 278, 279, 283, 284, 325, 326, 372, 373, 394, 395, 425, 426, 458, 459, 492, 493, 516, 517, 590, 591, 628.
• Required sources:
  1. A comprehensive episode guide with original air dates, such as the saga-specific pages on the One Piece Wiki (e.g., Sky Island Saga, Water 7 Saga) or other reliable anime databases like Wikipedia or IMDb.
• Priority: Low

Action Plan

1. Continue the systematic search for episode air dates by navigating to the next relevant episode guide on the One Piece Wiki, specifically the "Sky Island Saga" page, to find dates for episodes 107 through 206.
2. Proceed to subsequent saga guides ("Water 7 Saga", "Thriller Bark Saga", etc.) to gather the remaining air dates up to episode 628.
3. Once all necessary air dates are collected, compare the derived year ranges with those in the user's OP and ED tables to make a final determination on their accuracy.

Let me check the Sky Island Saga episodes next.

I need to check the Water 7 Saga episodes next to continue gathering air dates.

I need to check the Thriller Bark Saga episodes next to continue gathering air dates.

Let me check the Enies Lobby Saga episodes to find the missing air dates.

Verified Conclusions List

Item 1: 片尾曲(ED)更新情况 (Regarding the "使用时间" column for ED1-ED10, ED15)

• Preliminary conclusion: The "使用时间" (Usage Time) column for these ending themes is mostly accurate, with some minor discrepancies. The user's note about potential errors is valid.
• Source support highlights:
  1. The One Piece Wiki's saga-specific episode guides provide the original Japanese air dates for the boundary episodes.
  2. ED1 (eps 1-30) ran from Oct 1999 to June 2000. Report: "1999" (Partially correct).
  3. ED2 (eps 31-63) ran from July 2000 to March 2001. Report: "1999-2000" (Inaccurate).
  4. ED3 (eps 64-73) ran from April 2001 to June 2001. Report: "2000" (Incorrect).
  5. ED4 (eps 74-81) ran from July 2001 to Sept 2001. Report: "2000" (Incorrect).
  6. ED5 (eps 82-94) ran from Oct 2001 to Dec 2001. Report: "2000-2001" (Partially correct).
  7. ED9 (eps 133-156) requires the air date for ep 133. Ep 156 aired on June 8, 2003. Report: "2002" (Likely inaccurate).
  8. ED10 (eps 157-168) ran from June 15, 2003, to Oct 12, 2003. Report: "2002" (Incorrect).
  9. ED14 (eps 207-230) ran from Oct 31, 2004, to April 24, 2005. Report: "2004-2005" (Accurate).

• Consistency of source conclusions: consistent
• Requires further verification: yes

Supplementary Verification List

Item 1: 片头曲(OP)更新情况 and 片尾曲(ED)更新情况 (specifically the "使用时间" column)

• Reason:
  1. The verification of the "使用时间" (Usage Time) column is still incomplete. Air dates for many boundary episodes are missing, preventing a full assessment of the accuracy of the year ranges provided in the user's report. The previous search strategy of navigating saga-by-saga on the fan wiki has proven inefficient and has hit dead ends.
• Key facts to ascertain:
  1. The original Japanese air dates for all remaining boundary episodes for both the OP and ED themes to confirm the year or years of their usage. This includes episodes: 47, 48, 107, 115, 116, 118, 119, 132, 133, 169, 181, 182, 195, 196, 206, 246, 255, 256, 263, 264, 278, and all OP boundaries from 279 to 628.
• Required sources:
  1. A single, comprehensive episode list with original air dates, such as those often found on Wikipedia for long-running anime series.
• Priority: Low

Action Plan

1. Conduct a targeted search for a "List of One Piece episodes" on Wikipedia, which is likely to contain comprehensive tables with original Japanese air dates for each season.
2. Navigate through the season-specific lists on Wikipedia to locate the air dates for all remaining boundary episodes needed to verify the "使用时间" columns in both tables.
3. Compile the collected air dates and compare the resulting year ranges against the user's report to make a final determination on the accuracy of the "使用时间" data.

Let me search for a comprehensive list of One Piece episodes on Wikipedia.

Let me search for a more specific list of One Piece episodes with air dates on Wikipedia.

Based on my research, I now have enough information to provide a final answer about the accuracy of the data in the original post.
