Based on the numbers above:
- Updates in General - we tend to have the most number of them on Fridays (26), followed by Mondays (22), Wednesdays (17), Thursdays (16), Tuesdays (15), Saturdays (8), and the least on Sundays (4).
- Transitional Updates - we had the most number on Mondays (14), followed by Fridays (13), Thursday (11), Tuesdays (9), Saturdays (8  ), Wednesdays (7), and the least on Sundays (3). ), Wednesdays (7), and the least on Sundays (3).
- AIPs - we had the most number on Fridays (6), followed by Thursdays (5), Wednesdays (4), Mondays (3), Saturdays (2), Tuesdays (1), and no AIPs on Sundays.
- SAs, we had the most number on Fridays (9), followed by Tuesdays (4), Mondays and Wednesdays (3 respectively), Saturdays and Sundays (1 respectively), and no SAs on Thursday.
- DMs, we had the most on Tuesdays (6), followed by Fridays (4), Thursdays (3), Wednesdays (2), Sundays (1), and no DMs on Mondays and Saturdays.
- Landing Interview Invitations - we had the most number of them on Mondays (4), followed by Wednesdays (3), Tuesdays and Fridays (2 respectively), and none on Thursdays, Saturdays and Sundays.
So 
Friday is our 
winner in terms of getting updates in general, 
AIPs, 
SAs and a 
runner-up for 
transitional updates and 
DMs. So if you are waiting for your 
AIP, 
SA and 
DM, you will be most likely to get it 
tomorrow or next 
Friday  
If you are waiting for your 
Landing Interview invitation, it will be most likely on 
Monday or 
Wednesday, and maybe on 
Tuesday or 
Friday (tomorrow).
And for those who are still waiting for their 
transitional updates, it will be most likely on 
Monday or 
Friday (tomorrow).
So have fun with the numbers and good luck, and let's hope lots of people get their AIPs, SAs, DMs and their Interview Invitations tomorrow!! 
 * some applicants had multiple updates in a single day so the number of updates per day versus the number of applicants who had updates per day won't be equal.
