Is that today's newer owner users might expect better than 98% accuracy. So there it is. What? The 98% accuracy. Let's see what that means.

Academic books get 600 words to a page, 400 is more common so let's stick to 400 and see how many errors per page.

I get 8 errors per page.

Hope this helps you see what you are in for. Yes it is faster than re-typing the content but some expected better.
