Interesting stuff. I looked up the Kelly criterion and while it is not really applicable to poker in general, seeing it as an approximation of the low stakes games here is actually quite reasonable. I also find the idea of “speedrunning” 10k to 1M quite intriguing… But there is always a trade-off between the expected number of hands it takes to reach the goal and the probability of busting, so I’m not sure how a meaningful formulation of such a challenge would look like.
Your rise from the starting chips to 280+ M in a week or so is quite impressive. How many hands have you played in total? (You can look it up under “Statistics” in the menu.) Would you say that you ran particularly hot at the elite stakes level? Would you mind sharing your bankroll graph (using this Chrome extension)?
