Apologies if this is considered a thread-hijack, but I am nervous about going through the early-filing option and have decided to wait for for the complete 3 year anniversary to pass. The calculator page now has "The information on this page is out of date."
The guide posted by the OP seems more "official", and to answer OP's question, I would just wait.
Nonetheless, is there a general feel for the "current climate" operating normally in regards to 90-day early filings?
