title: Does Amazon MWS Throtlling means you can update 15 records or execute 15 update API calls?
body: <p>I posted this question on MWS forum but, didn't get an answer. So, I'm posting this here hoping for an answer.
  Here goes:</p>
  
  <p>Hi,
  I'm an absolute newbie in to MWS and I'm trying to understand the throttling impact on my design.</p>
  
  <p>Taking an example of Submit Feed, it says that I can submit 15 <em>requests</em> at a time before throttling applies. 
  That's clear enough except for what a <em>request</em> means? On the face of it, it would mean one MWS API call: Which means I can send 15 AmazonEnvelopes before I run in to throttling. Correct?</p>
  
  <p>Now say I need to update 25 products. What I need is to send 25 <em>Messages</em>. The XSD for AmazonEnvelope specifies maxoccurs=unbounded. Which means I can put all the 25 messages in one envelope and have it count as one <em>request</em>. Isn't that the case?
  So, I'm should only consider (from the docs):
  "One good practice is to submit feeds with a size limit of 30,000
  records/items or submit feeds"
  If I'm doing nothing else, I can "potentially" update 30,000*15 items without throttling.
  Is this correct?</p>
  
  <p>Thanks in advance for any answers you can provide. </p>
