Respectfully, this article's title is misrepresentative because you're really talking about work efficiency, not estimation accuracy. That said, we should be estimating effort, not time. Except for the most trivial changes, time estimations are notoriously unreliable (I won't go into all the reasons for this, but there's plenty of info online if you want to research it). This is one of the big reasons Agile replaced Waterfall as the preferred software development philosophy.
So, I'm not suggesting you change the content of your article, but I think a title change would more accurately reflect the article's content.
