Timezone is EST. I may resolve some options late, so an absence of resolution doesn't mean i failed a particular day's challenge. I'll leave limit orders at 70%, and not buy NO.

See the previous ones for a rough idea of my success rate. I'm going down to 4h (from 5h last time) because uh baby steps.

day 8: Tough one. I went to my desk at 7:50pm to work, and got distracted by notifs til like 8:05, and then i was living in denial and working, so i worked like 4hours including going past midnight, so happy with that, but i didn't rly work 4 hours. also during the day I did non-work stuff that was good, so W day, but L objective filled. looks like i gotta start earlier than 7:50pm next time..

Btw, should i keep it open after revealing this to let ppl buy it to 0? probably not but lmk if you think so

Day 5 was a success btw, if the YES resolution yesterday wasnt clear.

Day 6:

I rigorously proved a few theorems involving sample moments of order k, and sample central moments of order k, of random variables, including the sample mean. All these concepts make a bit more sense to me now.

The thing i didnt realize yesterday which made the proof so confusing to me was that the Xis, Xjs, etc are purposefully organized so that i != j and so on, and they re sampled from a population randomly so are assumed to be iid, so the expectation of the multiplication of XiXj is just the expectation of each multiplied together. That comes up again and again
