Thanks, but I still don't see how that accounts for the difference in my buch points. It looks like my unplayed opponent was Morx during the week where the numbers got off track. Can you explain the specifics about how I went from 71 buch points after round 4 to 117.5 after round 5? Here are my own calculations of my scores if that would be helpful: https://snag.gy/O7Xeh8.jpg
I think the more important question is whether these changes affected all players in the same way, or if some players may have been disadvantaged relative to others.
Also, I don't get how no shows can lead to half points: Every result for a player is either 0, 1, 3, or 6, right? Since there are no fractions, the sum of such numbers can't be a fraction.
