As correctly indicated by Coolguysam, many follows that threads to clarify doubts on process and applications. Since the process takes 3 months, with minor variance of +/- few weeks, the timelines might be irrelevant compared to citizenship where the variance is huge (depending on processing office and security check clearances).
I had send mine early Nov and am expecting the OCI roughly by Feb only. I am not keen on tracking it unless if I dont get it before March 2017.
For any urgent travel, we still have eVisa to bank on.
Good luck!
