Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.

Now, remember that the above example was using the “Very Readable” setting of WordAI. Let’s see what content will be generated if we use the “Readable” setting. Just a quick note here that this time it took about 20 seconds for WordAI to finish the spin, so the setting we are playing with definitely has some effect and is not there just for marketing purposes:
If you are a writer, then you know that sometimes you are likely to get stuck trying to find that “perfect word or phrase”.

This gives us the opportunity to provide you quality articles with words and phrases that best fit in the context.
We know that you want more from your spinner so SpinnerChief 5 uses a new, unique, organic approach to spinning, one that grows with your needs. SpinnerChief 5's new method actually gets better the more it is used. No other spinner has it - it's the new, exclusive Statistical Replacement Technology (SRT). It works in a radical new way by selecting the statistically most appropriate synonym for any word or phrase. SRT works in a similar way to Google Translate - you may have noticed Google Translate is getting better over time with more accurate translations. This is because as the web grows, the sample size for Google Translate's database increases, and so becomes statistically more likely to use the correct wording when it translates. SpinnerChief 5 works in a similar way by polling its huge Cloud Thesaurus for the statistically best synonym. As the Cloud Thesaurus grows, so SpinnerChief 5 gets better and better at synonym replacement. Remember - it's exclusive, don't expect to see this kind of technology anywhere else. ONLY with SpinnerChief!
