My paper is undergoing its third revision in a journal, primarily focusing on applied mathematics. There are some technical parts in it, but nothing really out of reach.
The time line is something like this:
-Submission to the journal.
-Eight months wait for the reports. Reviewers provide in-depth and crucial feedback. Both reviewers express difficulty delving into details due to writing issues, a point with which I agree. The paper, particularly given my non-native English background, was poorly written, and I was not aware of Grammarly and AI tools at that time. Still, there was many other important in-depth remarks about the model. In particular, I was required to provide with some comparisons with other tools in the field.
-Resubmission (1st major revision).
- Eight months wait for the reports. One reviewer sent his report quickly, but I had to wait both reports to be sent to read it. This one has only minor remarks but expresses its satisfaction overall; he finds my comparisons interesting and is fine with the paper as such. The other one, who seem to be a native speaker, finds the paper better, but still challenging to read and poorly written. At this stage, I am in a situation where I do not want to make too many changes, fearing to touch to something that the first referee liked. Still, I manage to clarify the paper further by incorporating mathematical results, initially in appendices, into the main text, and I broke down fundamental notions into smaller pieces. Now I believe there is a significant improvement in the way to convey the insight.
-Resubmission (2nd major revision). -Eight months wait for the reports. The first referee expresses that he is satisfied. But now the other one is focusing only on LaTeX remarks and notational criticisms, maintaining that the core part of my paper is "incredibly technical" (come on...), too technical to delve into. I now start thinking this is an exaggeration and potentially procrastination. There's a lengthy list of recommendations for minor LaTeX adjustments and criticisms of my notational choices. But at this stage, trading a notation for another one is just trading one inconvenience for another one... The paper is now quite stable, and though I took into account some interesting notational shortcuts, this new version is not fundamentally different from the previous one.
-Resubmission (3rd major revision).
-Now I have been waiting for another four months. Nothing moved since then. I see that the first referee submitted his report in a few days (probably saying one more time that he is satisfied, at least I hope), but and am growing increasingly frustrated about the inactivity of the second reviewer. It has been over two years since the initial submission. The editor is very professional, friendly and responsible. He perfectly understands the problem, but he cannot do more than nudging the reviewer. Should I approach the editor once more? Last time I contacted him was six or seven weeks ago.
I apologize for posing a question that has likely been asked many times, but the extended waiting period seems unusual.
Thank you in advance for your suggestions !
