<p>SEDE has been a great tool to poke into SE data.  I have seen some saved queries on it.</p>

<ul>
<li><s>Is there a definitive [official] list of queries used for badges on there? </s><strong>[apparently not]</strong></li>
<li><s> Is there a way to distinguish/quickly find queries used by SE itself and not user-contributed queries?</s></li>
</ul>

<p>Since there is no definitive list, how many queries like this one <a href="http://meta.stackexchange.com/questions/57232/is-150-rep-cap-exceeded-alone-enough-for-legendary-badge/58192#58192">Legendary</a> are available from questions/answers on meta?</p>

<p><strong>Re</strong> badge queries (subset of question) > <br>
Keep in mind that some of the badges depend on information that is not available in the data dump (like sportsmanship, talkative and so on)</p>
