Findings

  • The pulses rate is fixed for 3.0U/h and is issued between 55-60 seconds and is given at the end of the rate phase 360 or 330.
  • The pulse delay is calculated using the start time of the resume basal not the real time.
  • The PPPP is calculated using the real time.
  • Most resume commands had a 55 or 60 second delay, which translates to the XXXXXXXX values: XXXXXXXX = 1-5s = 55 seconds delay and XXXXXXXX = 6s = 60 seconds delay
  • (SSSS/8) % 6 * 1.000.000 translates to XXXXXXXX value, where 0==6
