   HCX Flight Computer logs 500 points/second. Red is acceleration (feet/tsec/sec and G’s), Green is speed (feet/sec), Blue is Altitude (feet):
   
   Note the altitude spike downward at apogee (top right of blue graph). The redundant computers are programmed to deploy the parachute at apogee. The pressure of CO2 gas buildup leaks into the avionics bay and makes the barometric pressure sensor see higher pressure (which generates to a lower altitude calculation). Red g-shock on far right is from parachute inflation.

   And note that the red acceleration curve during the boost phase mimics the thrust curve:
