Wear Pattern in "Bedrock"

This is a symmetric and bell-shaped pattern of wear on the entry door to the restrooms at Rocky Gap Casino and Resort in Flintstone, MD (yes, Flintstone). We've seen this type of wear often, for example, here and here. People use the handle to open and pass through door, but many, likely on exit, place their hands around the edge of the door to pass through or hold it open for others. They can't reach too high and when they do it seems only fingers are used, leaving little wear.  It's also  uncomfortable to hold it open too low, again likely only with fingers. So most of the wear and likely many whole hands are used between these extremes causing much more wear. Top to bottom, little use, greater use, then little use generates the bell-shaped pattern wear.
