When estimating any future metric, it is important to consider any unforeseen events, and how these events may impact your estimate. For example, when forecasting a firm's sales revenues, you would want to consider the competition and what there product lines and pricing strategy will be over the forecasting period.

This will allow you to fine-tune your estimate, which will hopefully be more applicable, and provide you with a margin of safety.
