general_features:scaling_championship_points_based_on_games_played

The idea here is that boards that are played a lot have greater competition than boards that are not, so players should have a chance to earn more CP on popular boards. Although this is balanced by the fact that less popular boards are more likely to have more experienced players, and conversely popular boards are more likely to have lots of newbs (whose starting 1000 GR is higher than their true GR, and so represent easy pickings). But even so, getting into the higher ranks of popular boards requires competing against very good players, and so players who support this ranking change believe that rank #10 on WGWF is much harder to achieve than rank #10 on $UNPOPULAR_BOARD.

One way to think about finding an appropriate scale, is to imagine equivalent rankings between boards. For example, if achieving rank #5 on $UNPOPULAR_BOARD is roughly equivalent in difficulty to achieving rank #35 on WGWF, they should earn equal CP. More detailed discussion and comparison along these lines in the Comparing Rankings section below.

A semi-logarithmic scale is proposed to provide more CP to boards that have been played more.

CP Master Table - Proposal 1

# of plays Top Rank CP Min GR for top rank # of ranks that get CP
0 - 10
10 - 100 10 1250 5
100 - 1k 20 1500 10
1k - 10k 35 1750 20
10k - 100k 55 2000 35
100k- 1M 80 2250 55
1M - 10M 110 2500 80

The CP is a compromise between exponential growth & linear growth. It goes up +10, +15, +20, +25, etc. between categories. # of ranks lags one category behind to allow top ranks to have a difference >1 between ranks.

Most boards keep the 20/1500/10 that we currently have. Popular boards get 35 CP for #1. Very popular boards get 55 CP, WGWF gets 80CP, and in a few years will bump up to 110CP.

CP Master Table - Proposal 2

This proposal does not weight popular boards quite as heavily as proposal 1.

# of plays Top Rank CP Min GR for top rank # of ranks that get CP
0 - 10
10 - 100 15 1250 5
100 - 1k 20 1500 15
1k - 10k 30 1750 20
10k - 100k 45 2000 30
100k- 1M 60 2250 45
1M - 10M 85 2500 60

The CP is a compromise between exponential growth & linear growth. It goes up +5, +10, +15, +20, +25, etc. between categories. # of ranks lags one category behind to allow top ranks to have a difference >1 between ranks.

Most boards keep the 20/1500 that we currently have, but the top 15 would earn CP. Popular boards get 30 CP for #1. Very popular boards get 45 CP, WGWF gets 60CP, and in a few years will bump up to 85CP.

CP for maps with 100-1k games played

The 100-1k range would keep the current CP table:

  1500+ score - 20 Championship Points
  1450+ score - 15 Championship Points
  1400+ score - 12 Championship Points
  1350+ score - 10 Championship Points
  1300+ score - 8 Championship Points
  1250+ score - 6 Championship Points
  1200+ score - 4 Championship Points
  1150+ score - 3 Championship Points
  1100+ score - 2 Championship Points
  1050+ score - 1 Championship Points
  

Other ranges would require their own tables which have not been proposed yet, but would follow the same basic shape as the standard table.

Comparing Rankings

One way to think about finding an appropriate scale, is to imagine equivalent rankings between boards. For example, if achieving rank #5 on $UNPOPULAR_BOARD is roughly equivalent in difficulty to achieving rank #35 on WGWF, they should earn equal CP. If we have enough data points below we can use them to make sure the tables described above are fair.

Here are some proposed equivalent rankings. Initial values here are a complete WAG, and are more for illustrative purposes. Please feel free to adjust or discuss in the forums:

Board 1 Board 2 Board 3
# of plays Rank # of plays Rank # of plays Rank
100 - 1k 1 10k - 100k 10 100k - 1M 20
100 - 1k 5 10k - 100k 25 100k - 1M 20
100 - 1k 10 10k - 100k 40 100k - 1M 55
