If the new precip total is lower or higher than any total on the list, it is assigned quintile number 0 or 6, respectively. Otherwise, the new total is given the quintile number of the section it would be placed in. When the past data are such that it is not clear what section to place it in, the highest candidate section is chosen. Indicate the current condition of each element in the record. Blank means the value is presumed good.
Any value now given is presumed good.
Exceptions are precipitation and sunshine duration, which are based on totals.
