If a team competes every other competition, can we beat algorithm?

Don't know for sure. I don't know how their algorithm works and what the parameters are. But I imagine that if you are playing with a tough group of competitors, say Nemeses A, B, and C. and you forgo playing a Spot the Difference, the next comp, a Time Rush comp, you may drop to a lower group. So then your team does really well. Then the next comp, a Spot the Difference, you'll be right back competing with Nemeses A, B, and C, again. But if that is what you want, to skip all the Spot the Difference comps, and to get a lower group for the Time Rush, then maybe that will work. I hope you try it and let me know how well you succeed.
