Paper rejection probability after two round of major revision. I would like to know the paper rejection probability (very rough) after two round of major revision. At the 1st and 2nd revision, I have revised the paper properly according to the reviewer's comments. The reviewer has raised a new issue in the 2nd revision and the reviewer has recommended me to revise the paper again. I have revised the paper properly again and submitted to the journal. The number of assign reviewer for the paper is only 1 (Reviewer 1). The paper has been reviewing for 7 months.

In the 2nd revision, I could not understand the editorial manager paper status meaning. The paper status has changed from "major revision" to "with editor" after submitting the revised paper. After 1 week later the paper status has changed to "under review" and then after two weeks later the paper status has changed to "with editor". I have not received any email from the editor so far. This morning I have checked the paper status and I found that the paper status again has changed to "under review". I would be grateful if someone could help me to understand the meaning of the status.
In general, few editors would allow for several rounds of resubmission unless they would like to publish the paper. Therefore, the probability of eventual acceptance should be much higher than the base acceptance rate at the journal.

With regards to the status updates: "with editor" means that the editor is about to look at your resubmission and make a decision on whether to send it out to referees. "Under review" means that reviewers have been assigned. In some cases, it does not mean that the reviewers have actually agreed to reviewing. The switch back to "with editor" suggests that the reviewer has either declined to review the paper again or has completed the review. In the former case, expect the paper to switch back to "under review", in the latter case expect to hear from the editor soon.
