It was really a matter of deduction based on this information (which is available as a pop-up when you hover over your thread in the "Next Cashout" column of the "Posts" section of steemstats.com), the 85% drop shouldn't have occurred. After doing all the research I could on the subject, and checking out all of the history as it was recorded to my http://steemd.com/@winstonwolfe profile, there are no other reasons that I can surmise why this would occur. If there is an unseen reason, I would need to be informed of that.
