Since the post count is less than what it was back then I can only assume that the main reason for the high difficulty is the decline in steem’s price.
This makes the most sense to me as well.
Have you considered adjusting the WP formula to be a variable? rather than WP = countif SBD.rewards >= 100
to something like
WP = countif VESTS.rewards >= average.SBD.rewards or some formula based on the average amount people earn on a rolling average.
Hey blake! Yeah your formula would be better for seeing posts that are doing above average on the platform, this could be a good reference for bloggers.
Since my index was first created for personal use I only wanted to get an idea of the probability of landing more than 100 SBD on a post. The concept of a "winning post" is subjective since 100 sbd could mean a lot for some bloggers and nothing to others..
