Okay, I suppose I haven't made this clear enough. In the grand sense of, people win the lottery "all the time" and football teams come back from 40-0 scores in the last half to win the game "all the time", I'm sure this would be considered a regular event. So here's what's bothering me:
People do not see other people win the lottery all the time. The people are geographically in different locations. People win contests "all the time" but I don't know a great deal of people who do, not even with the huge online communities I'm a part of.
What you're positing here, is that a team, who was getting CRUSHED by over 300 points, was somehow mysteriously able to rally EXACTLY when their score hit 1 point, was able to hold that 1 point until the other team, which had been ANNIHILATING them, was down from 300 to 0, without the likely benefit of any communication other than typing.
Mathematically, the odds are enormous, that JUST as it ticks down to 1, this sudden turn around happens. This is on top of human nature, ESPECIALLY in this game, which is to give up when you are getting such a job done on you. And this rally all happened... because of some carries? And this is a "common event", which states that this incredibly unlikely scenario somehow happens on such a regular basis that people don't even consider it rare?
This would indicate one of two things really:
1: There is a "pause bug" in the Dominion system that makes that last tiny digit last longer so teams have a rally point. This could be true, but considering I've watched my team drop from 20 to 0 in about 20 seconds, seem unlikely.
2: That whatever was done is done so regularly as to entirely strip away the absurd statistical probability of it and make it a common event. Remember there is a difference here, between something that CAN happen and something that DOES happen, and often.
Thus, either way, it deserves to be looked into. If I came up to you and said that I've won the lottery jackpot, twice, and then proved it, you would be seriously questioning the validity and the sanctity of that lottery system. This is a similar situation. If this happens "often" then there is the possibility of an exploitable bug. It is possible that the system is not working as intended (I'm sure that comebacks are possible. But for it to happen that dramatically, that regularly? Is indicative of a problem). For all I know, it could be that besides three or four "groups", no one else has seen it happen and that probability was just overabundant and the other team was actually not saying that KIND of comeback happens "all the time" but some KIND of comeback.
However, the manner is suspicious. It wasn't WOW that was such an amazing comeback, woot! It was as if they already knew it would happen. Isn't that odd? I think it is.
