I have not proposed anything. I am against the move to 2 minutes. Please stop trying to push this onto me: it's not my decision at all. All I'm doing is acknowledging and ensuring that the metrics don't change halfway through the test.
The evidence is that a majority of people seem to want it. I've made my own opinion of polls, their use, and this poll in particular, clear to the admin team, but if it is good enough for them then it's their call to make. Not mine.
