This isn't true for the actual hyperfocal distance (not sure if you meant the actual hyperfocal point though) as the range of acceptable sharpness extends in front and behind (to infinite) the hyperfocal distance.Just to expand on this, hyperfocal is always from a point (dependant on aperture, focal length and acceptable sharpness) up to infinity.
In practice, if your chart and or lens markings give you a distance the lens is et to, acceptable sharpness should be from half that distance up to infinity.
If you set the lens to infinity, then theoretically, half of that range is lost as it's greater than infinity... which doesn't exist!
