While on an exercise bike I tried a shutdown and restart of a Sense watch.

 

Actual heart rate is displayed accurately after a few seconds and that lasts only for about 10 seconds.

 

Over the next 40 seconds it climbs erroneously to almost double and remains inaccurate.

 

There is something clearly and seriously wrong with the way the algorithm works.

 

It needs fixing urgently. 

 

[During the same time an older Versa was consistently showing the correct heart rate without any difficulty, as confirmed by an ear lobe monitor]
