Calorie tracking with workouts are horribly wrong

Has anyone else had this issue?

The calorie loss during workouts are being tracked really off. I’ve used the Apple Watch & whoop and both had a 7-10% difference but this ring is nowhere close to it.

For context:

A 45 minute squash game on the Apple Watch show 450 calories, whoop would be 500 calories and this ring is showing 180 calories.

I’ve tested this across multiple occasions.

The heart rate during workouts doesn’t go beyond zone 1 or maybe 2 when I’m sure of being in 3 &4 for much longer periods.

Outside of workouts, everything else seems great.
