To be clear, you posted a chart written by Firstbeat (the company providing the algorithms for calculating energy expenditure). It is an older chart and the row you highlighted refers to beat by beat HR recording. Garmin heart straps don't support this as far as I know they just supply the HR level once every second.
There's no doubt that the Garmin 500 has an improved calorie estimate and it works reasonably well for some people but it is not within 10% accuracy for the everyone and produces fairly large errors for some people.
