We recommend leaving comments on your reasoning for assumptions. This makes your valuation much more objective and easier to understand. Make sure to mention sources for multiples or discount factors you have applied.
In the later versions of the product, you will recognize that a “digital coach” will tell you if a certain assumption seems to be higher, in line with, or lower the market average. Users will be also provided access to a market data center, which will help to benchmark their assumptions prior to a valuation.
