Registration Opens for Round 2021-3 (3)
Registration is now open for the third round of Lagrange Points. Contact me either here or on OGS with the number of games you desire and I’ll add you to the list.
OP and Wiki
As the edit period for the first 3 posts of this thread has expired, I requested a mod to wiki the rest of them. Feel free to add to the Index, but I would request that you please refrain from editing the OP itself. In the worst case scenario, I can just put the rules in a pastebin and link to it, but I’d prefer the convenience of just having it here.
Previous Poll Results
The vote was overwhelming for allowing matchups between closely-rated players, so there will be no restriction regarding that.
Maximum komi size had more diversity.

I guess this could be seen as supporting the hypothesis that a very wide range of reverse komi works, but smaller values are best, but that could just be confirmation bias. Mean is 156, median and mode are both 120, and geometric mean is either ~21, or my calculations are in error.
Rating Fiasco
So the reverse komi was whack in round 2, that much is certain. I’d also like to keep some closer ties to the OGS rating system both so that people who regularly participate in Lagrange Points can be more confident in how to estimate appropriate reverse komi between them and another person on OGS who hasn’t played in Lagrange Points before, and so that we can take advantage of all the work which has been put into the OGS rating system instead of reinventing the wheel which, in retrospect, was a very silly idea indeed.
So it’s back to calculating directly from OGS ratings, but with an offset which only changes by 1 point for every won or lost game. So if you have a rating offset of 5 points, your reverse komi will be calculated as if you are 5 points stronger than your OGS rank indicates, regardless of how much stronger that OGS rank has become.
This is essentially a more straight adaption of the Japanese Points Rating system, but tied to the OGS ranks.
This will change very slowly, so from now on (or until further notice), players may request prior to the beginning of any round (when you’re registering is a good time) a rating offset adjustment. Suggest either a relative (I think I’m a stone stronger than my rating is suggesting) or absolute (I think I’m about a stone weaker at reverse komi games than I am at even games) rating offset, and give your reasons why you think so. All adjustments subject to veto or counter-suggestion, of course.
If this system ends up sticking, it may eventually fall out of sync, with “0” rating offset being either stronger or weaker than the typical new player joining Lagrange Points. In that case I will add or subtract the same number of points from all players’ rating offsets, with a cap on how much an inactive player’s rating offset can change with successive adjustments to prevent any unforeseen degenerate behavior in that case.
Hopefully this saner system proves more, well, sane. Thank you all for bearing with me during these wrong turns.
