Our rating system has been discussed many times over the years, let me make some comments with the website and administration of our league in mind.
- FIDE determines initial ratings based on the performance of the first event (e.g. tournament - several games). We do not do this, and it would not be feasible for the IPL considering the many new players each season, and that they can join the league by playing just 1 game in any week of the season.
- For a 2000 player to lose 70 points in one day he or she would need to lose 3 times to a 1600 player (2 singles and 1 doubles). Arno, how many times did this happen in the past?
- With the current website code, asymmetric results are not possible. Less points lost by the higher rated player would mean less points won by the lower rated player.
- Already now, many members of our league do not fully understand, how ratings are calculated. I see no point in making this even more difficult.

Well Arno, here is the good news. With your current rating, you would need to lose to a 1245 rated player to lose 31 points in one game, and we do not have anyone rated that low in the league. And if we had (such a player), and you would (lose), then you probably would deserve to lose the 31 points.
