8 teams in top 10 and lost 8 out of 22 maps.
They didn't win their maps convincingly. There were some maps that they won convincingly, but far from all.
Astralis got 349 points for winning DHMM.
10 teams in top 10 and lost 1 out of 10 maps.
They won all of their maps convincingly or really covincingly and the one they lost, they only barely lost.
You see the difference? The difference is approximately the same as the point difference, if you ask me. Don't think about the ranking itself, think about the difference in points earned by winning big event.
