title: Firestore limit on updating data about once per second; why do I seem to be able to go past it?
body: <p>Firestore <a href="https://firebase.google.com/docs/firestore/solutions/counters" rel="noreferrer">documentation</a> and the <a href="https://firebase.google.com/docs/firestore/quotas" rel="noreferrer">quotas chart</a> show that a document can only be updated about once per second. Why do I seem to be able to update a document more than once per second with no problem? </p>
  
  <p>I tried a simple "for loop" and all writes seem to go through: </p>
  
  <pre><code> const db = firebase.firestore(firebase.app("prjID"));
   for (i = 0; i &lt; 10; i++) {
       console.log(`updating /test/test with test:${i} ${new Date().getMilliseconds()}`);
       db.doc(`/test/test`).update({ test: i });
   }
  </code></pre>
  
  <p>log shows : 
  <a href="https://i.stack.imgur.com/XSpZi.png" rel="noreferrer"><img src="https://i.stack.imgur.com/XSpZi.png" alt="enter image description here"></a></p>
  
  <p>I am wondering if someone knows the supposed server response when multiple write operations are attempted in less than a second i.e, beyond the limit that I seemingly can ignore?  </p>
  
  <p>If I am missing something and the limit means something different any explanation?</p>
