I didn't want to quote your post in the GP forum in particular. I only have the feeling that this is a posture of some people in the community to answer "The only thing you should care about is solving puzzles", when I point out some issues, or try to have some clever discussion on various subjects.
I'm glad to hear that you're open to the discussions and will follow them. I'm sure you'll make your best to try to improve the GP for the majority of players in the future.

And no I didn't know that your personal aspirations are in contrast with many current rules of GP, as you didn't speak about that publicly (or I missed the discussion).

As one of the core organizers of the first edition of Sudoku Mahabharat a.k.a. SM (2014-15), I'd like to share a few thoughts (mainly focussing on SM).

* SM's main goal is to select the Indian team via Indian Sudoku Championship, and to give an exposure to the 'newer' upcoming players via offline finals and SM playoffs. Which have been successful for 2yrs IMO.

* SM is primarily for Indians. International results and scores should be independent of this. The home page text says 'This is a national contest aimed at encouraging the best sudoku solvers of India to participate and experience the excitement, thrill and puzzling atmosphere on the lines of various national championships and the World Championships.' So, using international scores in any form is unnecessary. But having the scores on the score page gives an indication of 'where you stand' among the best players in the world.

* Being part of LMI over the years, we have experimented with many scoring systems via our monthly tests and annual contests. We've analyzed the points and ratings across the years, and finally decided to go ahead with simple top-player normalization for SM. There are two major reasons for this:
- It is more difficult and time-consuming to ensure consistent difficulty across rounds. And even more difficult when each round has a type-based theme.
- A simple normalization is better than nothing at all. And doesn't take any time.

* As a participant / solver in SM last year, and as per the discussions with my fellow Indian solvers, everyone I spoke to (which includes the top-20/25 solvers in India today) is happy with the current scoring system. So, I don't see any reason for things to change in SM.

* For international scores in SM, the only thing that gets impacted are LMI Ratings. Well, that is open to discussion as long as the Indian system remains the same.

To sum it up, I think SM is great the way it is.
We all have our personal opinions and preferences, and its perfectly ok to agree with some and disagree with others. I, too, personally didn't like the GP scoring system last year due to which I'm not participating this year. Its my personal decision and choice.

You make some good points Rohan, and I suppose this discussion is largely academic. In terms of ISC qualification, the ambiguities are likely to be so far down the list that it would be a real surprise if they then came good and hit the top 4 at the ISC - so it probably won't make a difference to A team selection.

Still, academic discussions are interesting, and having done the analysis prior to the "around the world" round at the 2013 WPC it's fair to say that the limitations of a simple normalisation scheme can be minimised so long as the relative point of normalisation isn't volatile between rounds. But, I also found that in order to give any more than a vague indication of "where you stand", then you also need to take into account the full distribution of solvers. From the data I looked at, the top score didn't do a good job of summarising the different distributions, even when the top score was sort of stable. Normalising by top score on this data resulted in some quirky results between the top 10% and top 50% of ranks.

I said before the scheme was risky. As with any risk, it is not guaranteed to materialise, but that shouldn't absolve the responsible organiser from taking that risk into account. With themed rounds, I think you have an increased risk of volatility in the top score; and if Rohan didn't participate in one of the rounds then the volatility is practically guaranteed.

Is the date/venue decided for SM finals?

can some one tell me when will the registrations for ISC will start?

Any updates on the finals - is the date yet to be decided? Everyone in the Top 60 is directly in right?

To both of the last two messages, we apologize for the delay in starting up the registration process for the event. We had some difficulties finalizing a venue because of some complications with our planned one. The top 60 will get a chance to attend by default, and we will extend further only if the venue allows for the numbers after the top 60's details of attendance are confirmed. All other details will be announced soon, tentatively expected by first week of May.

SM/PR 2017. Would you be sending invites to all those who qualify as per the rules or is it a general registration by all & any one ?
Request to please also clarify - Apart from the TEAM A B C from India for the WSC/WPC based on the Nationals can and how do others participate in it as guests ?

Hi. As per the below post in the same thread, the Top 60 will be invited for the Finals at the beginning and further invitations will be sent only after the receipt of confirmation from the Top 60 and if venue restrictions permit.

The second question will be answered by the WSPC organizers.

In general, we have covered our decisions on Participation limits for WSPC in the relevant topic on the WSPC website - http://wspc2017.logicmastersindia.com/forum/forums/thread-view.asp?... As hosts, LMI will be following the same considerations we have set for other countries - we will have an A and a B team, but further than that, we will only reach out to participants if the venue restrictions permit the same after considering overall registration numbers. Also, any priorities and other considerations will always be made according to the rankings of the Indian Sudoku/Puzzle Championship. You can also find other information about guest fees and so on on the WSPC website - http://wspc2017.logicmastersindia.com/

Its pretty clear that Team A for WSC/WPC will be selected through this offline events, i.e., Top 4 contestants of ISC/IPC. But, how the Team B for WSC/WPC will be selected??

Just like the previous year, Team B will comprise people who finish in the top 4 of TIMES sudoku Championship(provided TSC happens).If there is a overlap of contestants between the finalists of TSC and SM , then people further down the ranks in SM finals will fill the remaining spots.

Team B selected via this mode (TSC or SM/ISC as the case maybe) will be representing WSC only or both WSC & WPC. Or there is Team B only for WSC and no Team B for WPC.

Team B selected vide TSC is for representation only in WSC.Team WPC(A/B/C) will consist entirely of persons finishing at the top of the table in PR finals.But keep in mind that the existence of B and C Teams is ONLY if the venue permits that . You can also read through the poll discussion http://wspc2017.logicmastersindia.com/forum/forums/thread-view.asp?...
to know more.

ETA : The top inexperienced contestant from ISKL would also be sent an invite for B Team . Check under the prizes header in the following link .

Hi, Can you tell how the schedule will look like on 29th? like what time the event will begin and end? will help in planning the travel.

Hi. It will generally be a day-long event from 9 am to 6 pm including Registration, Prize Distribution etc.

Would we have a sample booklet for the offline finals on Jun 29th?

When is the IB for ISC/SM finals expected??

I estimate that it will take 2-3 more days, but I'll send a mail tonight with some updates, and also a note on the general format which will be useful to prepare for. (Same for IPC)

All the best to everyone for the National Finals.

For everyone's reference, below is the Google Maps link for the event venue.

Quality Inn Sabari, T Nagar
