so lets say you are driving to a city....any city...chicago for example, and you see signs along the way showing how many miles away the city is, for example:

Chicago - 237

etc...
so you keep getting closer to Chicago, until the sign says

Chicago - 3

when 20 minutes later, you see another sign:

Chicago - 5i

then:

Chicago - 17i

Something is definitely wrong....
