Please help me. I'm confused. If the scores for the Global Ranking are normalized to 100 for the top score each month, why doesn't Shadowdale have a Ranking of 100? Seems to me he's been perfect so far. (So far - I'm still hoping to beat him someday ... hope springs eternal)

Thanks

This explanation is going to be a bit technical, so I hope you'll understand it. <IMG SRC="http://forums.civfanatics.com/ubb/confused.gif" border=0>

Every time a GOTM has been played, the Global Ranking (GR) score is being calculated using the following formula: New_GR_Score = 0.7*Old_GR_Score + 0.3*Normalized_GOTM_Score

Now, when the first GOTM was played (actually the second, because the first was a beta game), the old score was zero (because there was no old score).
So the GR Score became: 0.7*0 + 0.3*Norm_GOTM_Score.
In Shadowdale's case: 0.7*0 + 0.3*100 = 30

Now for the next GOTM (also Shadowdale's case):
0.7*30 + 0.3*100 = 21 + 30 = 51
Next (last) GOTM:
0.7*51 + 0.3*100 = 35.7 + 30 = 65.7

It's all because everyone started with a score of zero, and Shadowdale too. Theoretically he can only get 100 in the Global Ranking if he has played an endless number of games and won them all. <IMG SRC="http://forums.civfanatics.com/ubb/rolleyes.gif" border=0>
