Specious bit of hand-waving featuring made-up numbers. My rule-of-thumb is to disregard people who plead virality, especially if they call themselves marketeers.

High sales get you into the top 10 lists which is really worth having (you can call that viral if you're desperate), otherwise high sales increases both the support burden and the likelihood of negative reviews.

However, an app like this has niche appeal (writers) and there is no doubt that exposure within that niche is beneficial. So word of mouth is important, but is not gained by simplistic approaches. Promotion within the niche is likely to be more productive than promiscuous price cutting. For a game, a different strategy would be appropriate.
