title: "Optimum" sampling interval of sensor system
body: <p>I am working with a system, <code>S1</code>, where many remote devices report in to a central server at constant intervals, <code>f</code>. Each device reports asynchronously with the rest of the system. </p>
  
  <p>The (complete) state of <code>S1</code> can be queried via a request-response API.</p>
  
  <p>Is there an 'optimal' frequency for another system, <code>S2</code>, to query <code>S1</code> that balances resource consumption and concurrency between <code>S1</code> and <code>S2</code>?</p>
  
  <p>A naive reading of Nyquist-Shannon leads me to <code>0.5f</code>. Is there a better alternative?</p>
