Indoor training not recognizing no or weak activity

Doing a very hard boxing training for 1h & 30min gave me 150 activity points. I left the activity running also after the training while driving back home. For cca 30min car drive I received additional 100 points. I used Indoor Cardio activity.

Previously on a apple watch it happened to me that i forget to turn off the exercise, but I would get a notification to turn it off.

Either the activity points should be counted differently if there is no actual activity, maybe based on heart rate or movement…, or to receive a notification that there is reduced activity.

Happens unfortunately after exercise to forget to turn it off, and in a competition it would not be fair. Also somebody could misuse it to collect points.
