One minor nit to pick, I think the rakes should be uniform across identical buyin events for all WSOP events (e.g., all $10k's are 6%, all $1500's are 10%). Those are laid out at the bottom of the WSOP pdf schedule.

And a quick comment, for what it's worth. I think this is a useful analytical tool, but I hope people will take it with a grain of salt rather than thinking a marginal difference of a couple "S-points" is reason enough to play one event over another. Factors such as your table draw will be much more significant than event structure. It's also worth noting that the score is agnostic as to buy-in amount, prizepool and rake (although rake is displayed) and really just favors length of play above all else. I understand the theory that a more gradual, deeper structure allows skill to triumph over variance more than a turbo. But I could theoretically run a $200 tournament with the same S-points as the Main Event simply by using the ME structure and starting stack. But would it really be worth your while to play a $200 tourney with 120-minute levels that starts 300BBs deep? At some point it would be a better use of a skilled player's time to play a $1-2 cash game than to grind through a two-day low-buyin tournament with a modest prizepool.
That's not to criticize the effort. There's clearly a material difference in the play in a tourney with a 100 score versus a 50, so this is helpful research. But it's just to say that this is only one data point to consider. As for me, if I'm considering two tournaments with identical buyins, I'll think about how strong I think the field will be at the two venues, the rake, the potential for a big payday from a large prize pool, convenience, etc. It's hard for me to imagine all those factors being so equal between two events that I would look to a few S-points of difference to make the decision. But if it works for other people, that's valuable.
