[D] ICML Rebuttle Acknowledgement

I've received 3 out of 4 acknowledgements, All of them basically are choosing Option A without changing their scores, because their initial scores were already positive. Meanwhile, the 4th reviewer had already given me a 3 and still hasn’t replied.

What frustrates me is that I didn’t just clarify a few points. I ran a lot of additional experiments and wrote proofs to address every request they raised. So is this really how the process is supposed to work? Reviewers can ask for as many edits, experiments, and proofs as they want, and in the end all you get is “thanks for your response” with no score update?

I’m trying to understand whether this is normal or if I just got unlucky.
