Thank you.
Hi,

Is this sentence correct? "The version is better than the compared version by 4%"

Thank you.

If you say 'the version', it sounds like you expect me to know which version you are talking about. I don't.

I'd expect eg this version.

It sounds odd to say 'better . . . by 4%'. What does 'better' here mean?

It's a shortened sentence from an article from a friend of mine. The reader would know the context therefore I don't expect "The version" to be a problem there. However, I had the feeling that you'll have an objection to it. I'm sorry, I should have changed it to "This/that".

To the point. The context is very difficult to understand since the article is about IT stuff from a university. But imagine that a method has a 70% accuracy and another method has a 74% accuracy. Can I say that the second one is "Better by 4%"?

Another example: "I'm 18, my sister is 20." Can I say: "She's older by 2 years than me."?

Another: "A winner of a race came to the finish 10 seconds before the second racer." Can I say "He was faster by 10 seconds."?

My dictionary has a similar example, but I've never said anything like this before so I'm quite unfamiliar and doubtful about these kind of sentences.

Thank you.

Hi,

To the point. The context is very difficult to understand since the article is about IT stuff from a university. But imagine that a method has a 70% accuracy and another method has a 74% accuracy. Can I say that the second one is "Better by 4%"? I suppose so, but why not say 'is 4% more accurate'? I guess the context would explain how accuracy can be measured so precisely.

Another example: "I'm 18, my sister is 20." Can I say: "She's older by 2 years than me."? Yes.

Another: "A winner of a race came to the finish 10 seconds before the second racer." Can I say "He was faster by 10 seconds."? Yes.

My dictionary has a similar example, but I've never said anything like this before so I'm quite unfamiliar and doubtful about these kind of sentences.

Note that 'faster' and 'older' are more specific words than 'better'. That's why I suggested 'more accurate'.
