Every GPS devise has its own built in maps and will use their own maps to navigate between waypoints that you import into it.
They also have algorithms that the software will use to calculate that trip, and most give you the option of choosing shortest distance, fastest time, avoid hiways, avoid tolls, etc.
So, depending on your selected GPS settings your unit may or may not follow your "computer" map exactly.
As you mention, adding more waypoints is one way to "force" your GPS built in map to stay on the course that you viewed on your computers mapping software.
Adding waypoints at every turn might be a little over kill in most cases.
It all depends on the route you want to take. In areas where there might be lots of ways to get from point A to point B, you might need more waypoints to follow your course exactly.
In rural areas, in most cases just about any map or GPS will use the same route to get from A to B, then you don't need as many way points.
After you use any mapping software (Ride Planner, or others), you will get a feel for how it converts to your model of GPS built in maps.
Also, keep in mind that your GPS will need map updates from time to time in order to stay current.
You might find a road on your computer mapping software that does not exist in your GPS map.
In that case you will never get your GPS to follow a road it does not know about.
A GPS map update will make these things less of an issue.
