I was going to share a chronology of my experience but it literally mimics the nice, detailed summation by dino33 (see below) so I'm going to skip the full details of the status/progress timeline. I'll simply affirm here that my experience with the OCI application - I'm a native born US citizen so no precursor renunciation step for me - was similarly quick and much faster than expected. I'm impressed by the seamlessness: no hitches, no glitches... as long as you follow the instructions (which admittedly seem onerous but doable if you just go step by step).
I completed my application on 4/10/19. Express mailed my documents via UPS to CKGS in NY the next day, the US passport was returned literally 2 working days later on 4/15/19. The OCI approval in Delhi took the longest elapsed time - 24 calendar days or 17 business days - they "acknowledged" it on 4/13/19 when the clock starts and they were done processing and approving it by 5/7/19. The printing and mailing steps were super fast from there.... got my OCI in hand today 5/10/19.
Although the standard promise/disclaimer on turnaround time on the GOI website (
https://ociservices.gov.in/welcome) is 60 business days, the CKGS website implies a much faster aka 25-35 business day turnaround for NY folks (
https://www.in.ckgs.us/faq/oci/processing-time-as-per-categories/1058/what-is-the-processing-time-for-a-new-oci-card#1058). I think NY in particular might have the ability to print and physically produce the cards locally as the final steps were lightning fast and the document is issued/signed by the folks at CGINY.
Bottom line: from first online app/web token to OCI card in hand was just 30 calendar days, 22 business days!
Thanks CKGS and CGINY (and MEA Delhi) - pleasantly surprised.
