As you can see, I didn't make any wrong words but my accuracy percent was only 76.68%. That's totally not matched at all. Please help me check! Thank you.

Hello,

Actually, the current calculation system for accuracy is correct.

Let me guess, you type in Vietnamese and use UniKey? The problem comes from this software. It lowers your accuracy because it deletes some letters to replace them with the expected letters, which automatically creates corrections.

For example, to type the word "nắng" with UniKey, you have to type "nawsng", don't you? But when you type "w", the "a" is deleted and replaced with "ă" (thus 1 correction) and when you type "s", the "ă" is replaced with "ắ" (thus another correction), which makes at least 2 corrections for this word. But if you type this word this way: "nangws", it will return 6 corrections because "ang" and "ăng" will be deleted and replaced. And there are still other ways to type this word (like "nawngs" or "nasngw") that will give a different number of corrections (4 in this case).

Besides:

đ = dd = 1 correction

â = aa = 1 correction

ê = ee = 1 correction

ô = oo = 1 correction

And so on...

So whatever you do, even if you are perfectly accurate, using UniKey will cause corrections, making 100% accuracy impossible to obtain.

It's weird, but sadly the site doesn't seem to be able to tell the difference between a manual correction (made by a finger on the backspace key) and a virtual correction (made by UniKey) because it's ultimately the same type of operation: deleting.


However it might be possible for the site to detect certain sequences of keystrokes used to create certain characters, recognize them as specific combinations and ignore or subtract the corrections generated. But it would involve knowing all the possible combinations for each word, which is a huge work.

Hi Linsk,


Thanks so much for your explanation.


Hope there is a way for Vietnamese to get their correct accuracy in the site soon.
