After the market closes, I will calculate the time-weighted exponential mean of its probability (using the exact probabilities, not the rounded ones in the display). Here, "exponential mean" means the natural log of the time-weighted average of e^P, where P is the market's probability. In other words, it is the generalized f-mean with f = exp.

I will resolve it to YES if the final mean is greater than ln(e-1) ≈ 0.541, which is the exponential mean of all values between 0 and 1 and therefore theoretically the fairest cutoff point.

predicted NO

The final exp-mean was 25.57%.

predicted NO

The current average is 27.8%. Team NO is already guaranteed to win, and has been for a while.

@JosephNoonan can you recalculate what Id need to maintain to flip?

predicted NO

@MarcusAbramovitch 98.35%.

predicted NO

The exp-mean is now 35.78%. Team YES would need to bring it up to 81.36% for the rest of the time to win.

bought Ṁ300 of NO

Currently calculating a mean of 39.12%.

The exp-mean over the remaining period would have to be above 69.95% for YES to win.

predicted NO

Currently calculating about 46.4%.

This one uses the exact probabilities like the others or the rounded ones?

@deagol Oh, yeah, I forgot to specify that. I'll update the description.
