1.  All of the raw data on net advisory prices is rounded to the nearest cent.  Need to be careful when adding data in future years
that the same level of rounding is applied to new data.  This is distinguished from the display of NAP's to the nearest cent.
2.  All of the raw data on net advisory revenue is rounded to the nearest dollar.  Need to be careful when adding data in future years
that the same level of rounding is applied to new data.  This is distinguished from the display of NAR's to the nearest dollar.

4.  Ties in rankings are broken by alphabetizing on advisory service name.  Thus, do two way sort on price and name.
