Check the connection of the cable on the back of the speedo.  That is the
normal spot for that small range.

The other cause is a worn speedo cable that is starting to fray.  Best way I
have see to spot that is that the bounce is different.  The bounce from  a
frayed cable is usually broader range and is very sudden in its shifts. A
sudden 10 mph drop and then jump to 10 or more mph higher and then back to
normal and then again and again.

Planned insanity is best.
Remember that sanity is optional.
