Is the space between thoughts an indicator of meditative calmness?

In this answer, it is suggested that space between thoughts, less discursive mental activity, is related to relaxation and concentration. I know it is not advised to judge one's inner experience too much during meditation, and that inhibiting thoughts intentionally is not recommended, but would it be right to say that a period wherein thoughts are more infrequent signifies a calmer mind? Does the diminution of thoughts correlate with calmness?
