The rests should be a very slow wander, and deep breathing, for approximately the same time as you took for the 200m. You want to recover reasonably well so that you can run them fast.which is the purpose of the exercise.
A lot changes in 20 years, not least ourselves, so it's little wonder new things crop up.
I have been known to try and sing bass/baritone in choirs so I never get anywhere near singing a melody.
