Okay just because I am a massive geek I tried to do some analytics on the spreadsheet from last year to determine average wait times post Interview Complete.
(Sample = 23)
Average time from Int Complete to Decision: 11 days, Median 11 days
Std Dev: 8 days
Admit average time: 9 days, Median 8 days (s = 14)
Ding average time: 5 days, Median 5 days (s = 6)
And there were a couple of ED-->RD folks at longer than average (s=3)
So it's not a very reliable sample and it's mostly from early in the decision period, because the spreadsheet did not get updated later. Also please note there are no decisions from the week preceding Thankgiving.
So the key message is "Take your mind off hearing this week. Don't expect anything until 11 days after interview complete at least. Have a cup of tea and a lie down and enjoy your thanksgiving."
