Hi Matthew,
Please remember that connecting is an optional practice in stage three. You only need it if following gets very easy, and it does not sufficiently engage your mind.
You don’t need to actually count the time. I recommend starting simple and noticing if this pause is longer, shorter or the same as the previous one. Once you get the hang of this, you can do the same with the inhale. Once that is easy add the exhale.
You can do connecting continuously if you find it helps you stay engaged with the breath. The real purpose is to give your mind a challenge.
