    Hi Dan: I use the previous years RPCs in the high period compared to the
    baseline in the previous year to estimate the RPCS. If you have more
    time and two years or more of daily data you can build a time series
    model to estimate daily RPCS. For instance : you can build a three
    parameter Holt Winters (exponential) model , one to capture multi year
    trends , one for seasonal trends and a third one to capture short term
    high seasonality trends
