<i>The subscore at the bottom of the article for &quot;ecosystem&quot; was given a rating of 6 (out of 10). To me, a &quot;6&quot; would mean &quot;above-average&quot;.</i><p>6 out of 10 is <i>not</i> above average. If you got 6 answers right out of 10 on a test, you&#x27;d call that &quot;barely more than half right&quot;. This is how American review scores work: they&#x27;re based on school grades where anything below 8 is pretty much unacceptable.
