I'm guessing that the answer is NO. Now that they have opened up the ADR booking to 180 days out things just book up faster. However, checking back at 90 days out (or periodically) is probably a good idea since cancellations happen daily.
I think they do. At about 160 days, the only ADR I could get for Coral Reef on a particular day was about 4:30, or whenever dinner starts. A couple of weeks ago, I was able to change it to a much more reasonable (for me ) 8:30, and I could have chosen about any time that evening.
