Correct and Precise may have been better terms. By correct I mean a result that I have very high confidence in, but that is not precise enough to be useable. By accurate I mean a result that is very precise but with far less confidence that it is correct.

As an example, consider a damped oscillation word problem from first year. You are very confident that as time approaches infinity that the displacement will approach a value just by looking at it, but you don't know that value. Now when you crunch the numbers (the verbal process in the extreme) you get a very specific value that the function approaches, but have less confidence that that value is correct, you could have made any of a number of mistakes. In this example the classic wrong result is the displacement is in the opposite direction as the applied force.

This is a very simple example so it may be hard to separate the non-verbal process from the verbal, but there are many cases where you know what the result should look like but deriving the equations and relations can turn into a black box.
