Is my manuscript stuck in Lancet or are they pondering over a decision?

I sent a submission to an Elsevier Journal. The status have been "With editor" since a month. I have done a submission to other journal some months before and the "with editor" process was just a week. I want to know if it is normal to wait a long time in order to change of status.

What does it mean to go directly from "under review" to "decision in process"?

Submitted to journal----(after 3 day)--->with Editor----(same day)-->under review-----(after 16 days)-->decision in process.

I have submitted my manuscript in Elsevier, now its status becomes " Decision in progress". What would be the next procedure & percentage of acceptance according to your experience!

In general, Journals Impact Factor is released in the fourth week of June every year?

I have submitted my paper to one of the springer journal. For the first week of submission, the status was "with editor" and then it changed to under review for one week, then reviewers asigned for the next two days then again changed to under review for 10 days then finally to "required reviews completed". The status reviews completed was for one week and then it changed to with editor again for last 10 days. Now my question is if it is rejection then the editor would immediately send the rejection letter. Why the editor is taking time to decide? Is it a good sign or a bad one??

Any article submitted to any journal goes under review if found suitable and within the scope of that journal. However, after reviewers completed their assignments, the authors do respond to queries raised by such reviewers, it could be once or a series of reviewer-author responses. Finally, the editor in Chief finalizes the decision. In Elsevier, particularly, before this happens, the status of the article shows Decision in Process. My question is how long does it take for this status to change under an ideal situation? And If it took more than the expected time, what should the corresponding author(s) suppose to do?

I hope to get sound and convincing responses from eminent researchers and editors across the platform.

I would be happy to read experiences from early career researchers who have submitted their work to these journals and what responses did they get?

I submitted a manuscript to the journal then the status changed to With Editor After a certain period it was changed to the decision in the process. Does this imply a Reject decision?
