Yeah, this is a bit of an imperfect solution to a couple of intractable problems.
Last year a lot of people complained about 1v1 tourneys not being brackets (ie. no score reset between rounds.) This year, I had BW change everything so that all things that look like brackets actually were brackets. (Meaning that all head-to-head competitions like 1v1 and Polys had score resets every round.)
Then, this year, after the Olympics had already started, we found out that the Tribal algorithm can't handle eliminations, so BW had to take the eliminations out of those. Probably should have taken out the score resets at the same time, but neither of us thought of it. So, we ended up with a lot of tribal tournaments that have head-to-head matchups, no eliminations, and score resets. They are the bastard children of tournaments that were once pseudo-brackets but are not brackets at all now.
Last night all the remaining score resets were removed from those. However, doing it retroactively would probably result in more wrongs than it would fix, so it's not retroactive. In any of these Tribal tourneys with head-to-head matchups, score resets that already took place will stand, but score resets that haven't happened yet have been removed.
It's not a perfect fix, but best we could come up with given the rather chaotic way these Olympics have evolved.
