Really great post! I just wanted to point out one error:
number_of_block_per_week is constant, Steem generates 3 blocks per minute * 60 minutes * 24 hours * 7 days = 201600 blocks
This should say “20 blocks per minute”. The number of blocks per week is correct so it seems to be just a typo rather than a math error.
Hey, thank you for catching, it's a typo, updated. ;-)
