# Measuring error rates may reduce performance

To maximise practice time is to maximise error rates. But, unfortunately, carrying this habit from practice into perform (Practice-Perform duality) might be detrimental, given that it may induce frustration in a high-stake environment, forming a vicious cycle:

  1. Expected to execute a high performance
  2. Seeing errors, frustration
  3. Reduced performance
  4. Back to 1

You can easily spot this cycle happening to athletes in competitions.
