有誰知道嗎？Anybody knows why ?

［由於你在英文版發問，而不是免費資源版，所以我也用英文回答。］
[Since you raised your question in the English Board instead of the Free Resources Board, I shall give my response in English as well.]

MingLam，我知道原因，也有幸可以回答你的發問。
MingLam, I know the reason, and this is my honour to reply you.
［其實我經常有在你的帖子的意見欄有發表的，不知你是否知道。。。］
[Actually I always left my words in the comment boxes in your (answer) posts, I am not sure whether you noticed that...]

其實你的情況剛剛遇到一些尷尬的時刻。
Actually your situation is the one which reaches an embarrassing moment.

由於碩士級（台灣稱專家）和博士級（台灣稱大師）的分別除了回答數之外，採用率也是要求的標準之一。
This is because the difference in standards between 碩士級（台灣稱專家）and 博士級（台灣稱大師）accounts for not only the number of answers, but also the percentage of adoption.

你於現在這一刻絕對是博士級 4 級，不用懷疑，但為何系統會評定你為碩士級 1 級呢？因為你剛剛（於３題最佳解答前）才把採用率提升至 60%。
Your current level is in no doubt 博士級 4 級, but why the system would regard you as 碩士級 1 級? This is because you just reached the 60% threshold of adoption requirement, just before 3 questions you finished.

４３０／７１５　＝　６０。１４％　＞　６０％
４２９／７１４　＝　６０。０８％　＞　６０％
４２８／７１３　＝　６０。０３％　＞　６０％
４２７／７１２　＝　５９。９７％　＜　６０％

所以你最近才正式升到博士級。
Therefore, you was just promoted to 博士級.

但系統每天的凌晨（大概十二時至二時之間）才更新，所以你的知識檔案要明天才能夠升為博士級。
Nonetheless, the system only updates daily (in between midnight and 2 a.m.), so your profile will be officially updated tomorrow.

但如果你現在試在意見欄發表，相信你可以顯到為博士級 4 級。你可以試試。
If you try to post some comments now, I believe that the system can reveal that you are now 博士級 4 級. You can have a try.

因為我發現了意見欄的個人級別是即時更新的。
This is because I realized that the individual level of member is updated in time for the comment boxes.

真的很奇怪，你的檔案仍未更新．．．

It is really strange, your profile is still not updated...

You are correct, they consider the same word count for Chinese character and English character, then of course it is more efficient to use Chinese in this regard.

系統真是有問題啦......

奇怪~!!!

Ming Lam 兄，你的檔案沒有更新．．．

Thanks, I also hope that the Yahoo! system will improve.

Many of us hope so...

Congratulations!

The system is really strange.

^__^

For those who are interested Math will know yesterday was the Pi Day.
Thank you folks on commenting on this question.

To my surprise, I received a notice from Yahoo knowledge + database today telling me that I have been promoted to 博士 4 級. So the system finally corrected by itself. Wonderful.

我今天出乎意料收到奇摩知識+寄來一封通知，說我已升級成為 博士 4 級。想不到這系統原來還有自我修復的能力，不錯。

果然是隻好奇的貓，摸得清清楚楚！

I never realized that the above was English?
