| - Although the parachute predictor estimated a descent rate of about 6 m/s, we rounded up to 8 based on previous experience with the balloon remains interfering with the parachute function. The observed descent rate was 8.9 m/s. We could have rounded even higher. | - Although the parachute predictor estimated a descent rate of about 6 m/s, we rounded up to 8 based on previous experience with the balloon remains interfering with the parachute function.
