Its all in your mind ,the so called "troll" result (a phenomena I dont particularly believe in) can happen any day of the week and is no more frequent on the weekends if the posts of those claiming to have suffered from this phenomena are to be believed. Why dont I believe in it ? this is a game of chance really , a randomly selected number pattern determines the match results and all improving your team does is improve your chances of generating a higher random number pattern more often. All teams are capable of generating their own high number roll at some point although lower rated teams high roll may not be as high as higher rated teams. At some point your team will roll its low numbers and if this coincides with a lower rated teams high number pattern then you are a chance of losing the match or at the very least struggling to beat them. This number pattern generation has no association with the day of the week.
