If it is a Market Size case, and the context about "guesstimates" (i think it is). First of all, you need to reconcile your answer (est. earnings) to baseline from which it was derived. Example: what % does estimated earnings take from total earnings? Secondly, - as i understand, you're always expected to provide recommendations how to make your estimation more relevant. I don't understand how it is possible to start calculate historical ratios on the case interview.
What additional check should we perform to verify if our estimated earnings are realistic?

Calculate historical ratios (earnings to sales, gross margin, operating margin, earnings per unit sold ...) and compare them against the forecasted ratios. Ceteris paribus, the forecasted ratios shouldn't devate much from the historical ones.
