With 70-100 seats in Gwalior, chances seem low. Last year Chennai closed at 800ish Rank with 120 seats, I expect Gwalior to close around 1200ish Rank.
I ran a script on the baylor site and it came to around 180 unique colleges, then how come 269 unique college teams solved at least one sum? 
First let’s hope that we will get results by today 
Yeah, true. But I was in competition for Chennai, so not sure if I would get something from today’s result.
Waiting for Kharagpur and Amritapuri
I don’t think so. Kolkata declared for only for their own site. I think the same trend will be followed by other sites as well. Amritapuri hopefully today. Gwalior still stuck at 14th or 15th
. No update from Kharagpur.
No. This is not allowed AFAIK.
no update…
I am not even able to open their site
. But my guess is that they will be out either today or latest by tomorrow since results of 3 sites are already out.
i mean whether we are going for kolkata region or Kanpur region?
They have written that first team will be get Amritapuri , second one will get Coimbatore and so on. There are 49 entries on a page. On your page check if you are at odd or even. If odd then Amritapuri and if even you are going to Coimbatore. 
Won’t it depend on the teams as few may not register for it?
Yeah i also think it won’t be published today. No point in waiting anymore.
Yes, no more now. By Sunday all sites will publish I suppose.
I think not many will opt out of registration. But you are right, the above strategy will not work in guessing out the site you will be allotted. Unless the number of teams opting out above you are even in number.

As per regional website:-
You will receive the link by Saturday, the 18th. The list of confirmed teams with the site allotted will be published on 21st. We will publish the list of teams to fill the vacant slots based on the rank (criteria as mentioned below).
Chennai? Its onsite is earliest and its result is latest?
