But how can someone predict less than 700k week all December when the first week is up? Are we saying that the numbers are wrong? Just to clarify because it's an insurmountable logical trap for me. In other words, what metrics are we using; official announcements or chartz for making predictions.

I think people need to define what measures they are using for predictions and what source they will use to qualify it's accuracy. We know chartz isn't accurate but if we make predictions, are we bound to ioi 's results with respect to adjustments?

And when I called him out he said he is using 50k tolerance on that big interval.... so it isn't really above his range....
