Ken, I'm sure your chart is accurate for DX sensors and the given focal lengths.
It's just no good to me as a Canon shooter, because Canon doesn't have a 1.5x crop sensor. With a 1.6x crop sensor, the circle of confusion changes size and all the hyperfocal distances are different. Your chart tells me @55mm and f/8, my hyperfocal is 19m. But on 1.6x crop, it's actually 20m. Your chart is also no good for a four-thirds shooter or someone shooting full-frame, or APS-H (1.3x crop), or using a point-and-shoot.
The DoF/hyperfocal chart generator I linked to can create charts based on any of those sensor sizes and any given focal length.
