Do folks generally see a point swing of 50-100 points per game? That, plus the time off factor, can really tank your rating.
We all have good and bad streaks -- I drop 500 rating points in a single sitting, after losing 6 of 7 games. Then I had a turn of fortune in my unranked Gokdom games, then regained the points over two more sittings, winning 6 games in a row.
I mean, I get that I won and lost basically the same amount of games over the time period, so my rating "staying" the same makes sense. But because of the instantaneous changes, going from ~5300 to ~4700 to ~5300 in a three day period just feels wacky. And depressing, since I'm never going to break into the "good" category.
