The maximum heart rate might need to be increased (that is, update it to a higher value under personal information, save it and re-create the reports), if the person’s heart rate during the measurement is very high / close to their estimated maximum heart rate during normal physical activity (not some kind of maximal effort).  If the heart rate actually goes higher than the estimated value, the program will automatically update the maximum heart rate value.

In situations when the person’s heart rate level is generally high throughout the day, without the person engaging in actual physical activity (the analysis might show several hours of physical activity), it’s sometimes advisable to increase the maximum heart rate by 10-20 beats. Increasing the maximum heart rate in these types of situations improves the accuracy of the calculation of health promoting physical activity and training effect.
