"quality" being an arbitrary term in relation to their opponents ladder ranking. | ||

My guess is that it's a consequence of the bonus point system, high losses, low gains at the top of the ladder. Dayvie climbs in points because the bonus point system gives him more than he loses. TTOne loses more than/just as much as he gains from the bonus pool. It's fairly safe to assume that you are bound to lose points if you are at the top of the ladder and "only" have a 68% win ratio. | ||

It's not that trivial as an explanation of "Dayvie just played more favored people while TTOne didn't". If the system is good it should average out and you shouldn't have people with different win percentage of 4%+ with a combined sample size of over 400 games have similar rating. In this case it's even worse because the direction is reversed (lower win % --> higher score). The p-value for that has got to be miniscule. The explanation must lie in how the system matches opponents. I don't have that great of a knowledge about how it works, and would like to understand. | ||

+Blizzard is reluctant to give all details of their ladder ranking system because then it's possible it could be abused. Just thought with the intelligent TL userbase here someone could venture some plausible guesses to explain such non-intuitive results. | ||

Maybe TTone lost a lot of games to Dayvie? If you beat someone you gain a lot more points then what you would have won. Say Dayvie beats TT1 Dayvie gains 20 points and TT1 loses 10 points. Dayvie just gained 30 points on TT1 in the ladder. | ||

As for the bonus pool, I don't think it should make much of a difference because they probably started laddering at the same time, at the release of Starcraft 2. Thus they both gained the same amount from the bonus. I found this website which helps to explain the system a lot, http://lorehound.com/starcraft/starcraft-2s-battle-net-leagues-ladders-and-rankings-explained/ but it still seems to me that the data I see for rankings seems discordant with a well-designed laddering system. Another explanation that seems possibly plausible to me is that these two users play as part of two different Battle.net 'cohorts'. If TT1 only plays at night and Dayvie only plays during the day, this could somewhat explain how they could have different %ages with similar ratings. Do they live on opposite sides of the Earth? lol | ||

If best winrate -> best ranking, then ranking would be rather redundant. | ||
