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:
