I believe there may be an error in the Help screen for 'Stocks' where it says '2. you specify historical sales in the years up to the Base Year, and a survival lifecycle profile describing the average fraction of vehicles surviving as they age. Base year stocks of devices are then calculated automatically based on the sales and survival rate data.'

I believe 'Base year' here should be 'First scenario year'. Otherwise, I know of no way to enter data for years prior to the Base year. Am I missing something?

Hi Ralph,

You are correct that there is an error. The Stocks screen specifies that there are 2 approaches for entering stocks and sales data. This is outdated. At this time only the first approach is available.

You must enter the base year stock of devices and specify a lifecycle profile describing the age distribution of vehicles within that stock, together with the sales of devices in the base year.

Thank you for bringing this to our attention. We will address it shortly.

Best,

Tory
