It makes me wonder if there is an industry standard for how
viewfinder magnification is measured.

The common standard is the actual magnification (size of image as it appears in viewfinder vs. size as it appears directly without camera) when a 50mm lens is mounted on the body. Note that this is the same definition that used to be used with full-frame film cameras. This allows manufacturers to get away with quoting a larger number than if they'd shifted the definition to use a 50mm/1.6 = 31mm lens, the focal length yielding the same angle of view as the 50mm/full-frame combination but on an APS-C sensor body.
