I tried a VO2 max + lactate test - how accurate is my Garmin watch?

I did a number of fitness tests to see how fit and healthy I am, and compared the results to my Garmin watch.
Tests included:
- Resting metabolic test
- Body composition & skin fold test
- ECG
- Spirometry
- Lactate threshold test
- Vo2 Max test
