It Is logical for more teams to be stronger on weekends. Many of us are working adults. We have more time and more reason to train as there are association tournaments. Our bonuses might fall to 4 to 6 percent on weekdays but is more likely to hit max on weekends. I played like this initially as well.

I do not think the system is programmed to spoil our weekends as mentioned. For every loss, there is also a win. If you had a bad day, someone has to have a good day.
