Zoom Ratio vs %

Zooming the display appears to be a simply expanding a central portion of the un-zoomed display (zoom % = 0) to fill the screen, with no distortion of the expanded scenery. I wanted to know, for any zoom %, the ZOOM RATIO: - the ratio of the size of objects in the “zoomed” display to their size in the display with zoom = 0%.
I measured the zoom ratio for various % zoom. I’ve appended my numbers, plus a graph.
