Plot Description:
This autoplot attempts to provide probabilities of some month/year besting some previous month/year. These probabilities are built by appending all previous years on record onto the current month to date or year to date value. The theory is that the past provides an envelope of what is possible for the future. This autoplot is not an exact science as leap days and other calendar quirks can make an off-by-one situation with the data comparisons.3 Generated Chart
