For those of you who have been asking how accurate our Real-time YMPE estimates are...
Real-time YMPE estimates have an 11-year track record of successfully accurate estimates.
Changes to the YMPE are made in even $100-increments. We believe that a YMPE estimate that is within +/- one $100-increment of the ultimate official YMPE value is a successfully accurate estimate.
Since 2015, and for estimates beginning in May, Real-time YMPE estimates have successfully been within +/- one $100-increment of the ultimate official YMPE value 95% of the time.
For the full track-record going back to 2015, see the calculation methodology paper here:
