what's up brothers and sisters?

kinda funny when I was pitching to our stakeholders: "the worst case is we DON'T pay out a lot of money". well, that was a take me to the mountain event, but, in a way that's reality. we'd be HAPPY to pay 50K to winners. if it doesn't work out that way, we'll roll the cash pot over into new contests, and, by the way, not on same target prediction. It's up to all of you.

Please help me understand evaluation more precisely. Let's consider current LB#1 as an example. Why is it #1? All metrics from LB are far from being first, especially City & Global novelties. I thought the most important ones are Sharpe & City/Global Novelty, but seems to be false. So, what should happen to somebody to overcome current LB#1 and become new leader? And last question: Do you recalculate LB scores from time to time, or it remains consistent for the whole time of the competition? Thanks!
