title: largestChangeId being returned inconsistent?
body: <p>I'm using the drive change feed to find changes of files in Google Drive.  I have been experiencing some inconsistency.  I just tested using the API Explorer found here : </p>
  
  <p><a href="https://developers.google.com/drive/v2/reference/changes/list" rel="nofollow">https://developers.google.com/drive/v2/reference/changes/list</a></p>
  
  <p>On one user the largestChangeId returned was 1208, although when setting the startChangeId to 1208, the request returned 6 entries, including the change of 1208, and each other change being higher than 1208.  I also have the flags includeDeleted = true, includeSubscribed = false.</p>
  
  <p>I then tried on another user, the returned ID was 136023.  When using this value with the same params as above Drive returned 0 entries, which I expected.</p>
  
  <p>Then I tried on a third user, the returned ID was 8267.  Then setting the call again with the same params as above Drive returned 1 entries, which had the same change id of 8267.</p>
  
  <p>Note all three accounts are testing accounts on a test domain in which no documents are being modified or shared.  </p>
  
  <p>So three users three results making the same call.  Is this expected or a better question, what should I expect when making this call. In the documentation it states : " Change ID to start listing changes from. (string)".  When it says from and you are returned the highest ID I would expect 0 results to be returned.</p>
  
  <p>Thanks.</p>
