Advance look - Exploring the Steem blockchain: Who are the best curators?

According to a scoring method that I'm toying with (and assuming no errors in my code), here are yesterday's top-50 curators with more than 10 curation rewards. If I'm thinking about this right, the scoring should be independent of wallet size.

Since this is a first draft of code, please take it with a (very large) grain of salt. ;-)

Eventually, I hope to start publishing regular updates as well as the code I'm using, but it might be a while... Finding time to work on this has been a challenge.

Looking at the SteemDB curation history from a handful of accounts in the list, these accounts seem to be collecting curation rewards at a rate in the neighborhood of 20-26% of their staked SP.
