If the frequency is set to 1 then the RCC will more closely align with how you probably set up your main CBA (e.g., 10 years of impact estimates spread over 10 columns). Upfront impacts are assumed to be incurred at the beginning of every period and they are always assumed to have a frequency of 1. Upfront activities will start at period 0, so if an upfront activity spans 10 years it will have 11 total periods (starting at period 0 and ending at period 10). Ongoing impacts are assumed to be incurred at the end of every period. Ongoing activities will start at period 1, so if an ongoing activity spans 10 years it will have 10 total periods (starting at period 1 and ending at period 10). This treatment of upfront vs. ongoing activities may partially explain some numerical differences between your RCC and your CBA, even if both use an annual frequency of 1.         

If the frequency is set to 1 then the RCC will more closely align with how you probably set up your main CBA (e.g., 10 years of impact estimates spread over 10 columns). However, recall from above that upfront impacts are assumed to be incurred at the beginning of every period and they are always assumed to have a frequency of 1. Upfront activities will start at period 0, so if an upfront activity spans 10 years it will have 11 total periods (starting at period 0 and ending at period 10). Conversely, ongoing impacts are assumed to be incurred at the end of every period. Ongoing activities will start at period 1, so if an ongoing activity spans 10 years it will have 10 total periods (starting at period 1 and ending at period 10). This treatment of upfront vs. ongoing activities may partially explain some numerical differences between your RCC and your CBA, even if both use an annual frequency of 1.         

   

   

You may decide to use a frequency greater than 1 if the regulatory requirement specifies that the activity must be conducted several times per year, or if the requirement to conduct the activity is triggered by some other event that happens several times per year. if you enter an annual frequency of 1,200, then you are telling the RCC that you want to split every single year into 1,200 evenly spaced periods, in which the stakeholder count must be estimated and impacts must be discounted back to the PV base. Is that really what you want to do? That is probably not how you set up your main CBA. With 1,200 evenly spaced periods that means the RCC will estimate the stakeholder count more than 3 times per day. There is nothing mathematically wrong with this, however it is computationally intensive and it may not be necessary.
