Ed, what does this have to do with the original post or subject of the thread? Also, moderato is a tempo marking. Dolce is a style marking. How is it that "dolce" would throw you for a loop? Yes, there's latitude, but not when they have completely different meanings. (Yes, I realize that "dolce" is generally used when the tempo is slower, or "moderato," but it still has a different meaning.)
The truth is, most musicians could use more time working with a metronome. I can't even begin to tell you about all of the times I was playing as a praise band drummer where we'd come to a point of the song where the drums dropped out, and the remainder of the band couldn't maintain that same tempo for even a single freaking measure with me there beating time for them. Not one, single, measure. It was mind boggling to me that the average amateur musician's sense of time and tempo was that bad.
