Is your HRmax set correctly? Garmin defaults to the standard 220 minus age estimate, or 156 for a 64-year-old male.
The white paper states that if your estimated HRmax is 15 beats too low, the error is 9%.
If your HRmax is 15 beats too high, the error is 7%.
If your HRmax is exact, the error is 5%.
