Silly me. JerrySTL you nailed it, at least part of it. I had changed the mph to kph accidentally and didn't notice it. When I changed it just now the total distance number changed from 59.40 to 36.91, that sounds more like it. The trail measurement may be off some. 5.3 k is about 3.5 m.

ItsJustMe, you know I had the sensor and magnet near the hub and because I had changed the computer display from mph to kph, I thought I was getting a false measurement so I moved them out toward the rim where they are now. I will see how it goes and move it if I have to.
