In the app's calculation of collection value, we include some assumptions in pricing. In the export, we do not.

On the app - when a wine does not have a market value, we include the entered purchase price instead. When the wine does not have a purchase price, we include the average price of a wine in your collection in the total value calculation.

In the PDF export - the total collection calculation only includes the wines we have definite prices on and skips any wines where the field is missing.
