Dear Authors,

Both reviewers are in favor of publishing your paper as is. However, coincidentally, they both refer to the same final suggestion for an optional minor change. You can find the comment of Reviewer 1 below, while Reviewer 2 responded to me with: "The authors have generally responded well to the questions and requests for improvement of the manuscript. I would have wished a little bit more discussion on the point 12 that I raised, but the authors have dismissed this saying this would require a lot of additional work and they prefer to save this discussion for an upcoming article. Fair enough in a way, but they could in my view mention this as a note to say that further research will focus on the particular point raised. I leave it to you to decide whether to request this addition or not."

Given that also Reviewer 1 is referring to this, I would suggest that you slightly extend the discussion of future work in the conclusions, discussing possible improvements that could be included for stable and very stable... To allow this, I have accepted the manuscript subject to technical corrections

Congratulations on the very nice work.
Kind regards,
Johan Meyers
