Heart rate accuracy for "Sport"

[AlexC92]

Hello,

I have been previously using a Charge HR and used exercise mode when playing tennis. The HR tracking was pretty accurate going up to 190bpm:

Average heart rate 135 bpm

Time in heart rate zones

• 6 min peak
• 26 min cardio
• 20 min fat burn

Now I switched to Blaze which doesn't have a setting for tennis or a general exercise mode. After a tennis match which the tracker recorded as "Sport" I have:

Average heart rate 94 bpm

Time in heart rate zones

• 0 min peak
• 0 min cardio
• 21 min fat burn

Is there a way to improve the accuracy? It's essentially the same HR sensor, so where does the difference comes from?

Edit 1:

This is the monitored data after selecting an Exercise from the list intead of letting the Blaze autodetect:

Average heart rate140 bpm

Time in heart rate zones

• 3 min peak
• 28 min cardio
• 26 min fat burn

Blaze does have tennis setting, make sure it is enabled in the app
