Ann: World Voicemail Android Release, Initial iOS App Results, page-87

I just wanted to point out that in the announcement, the phrase states "positive returnof up to $300 - $400 upfront revenue"

The key words are 'up to' like when a store runs a sale and things are 'up to 50% off.'

Unintentional as I'm sure it was, in your response here Shane, you state "around $300 - $400 of revenue per day (since 19 August)" which is clearly false. From the 19th of August until the 5th of September it is clear from the FB charts that NOR is making approximately $125 or less per day (parts of graph reach around the $250 mark and actual conversion rate is 50% of this, so $125ish maximum). During the week of September 4th-11th, the graph shows revenue hit around $750 (with the 50% conversion that's actual revenue of around $375) for one day, and around $800 ($400 actual revenue for one other day). 

Just my personal opinion, but it may be a little too early to be estimating that the app will turn-over $300-$400 revenue every day, when the graph provided in the announcement shows this has only been the case 3 days out of 24 total. The graph has a distinct dip right after the first spike, and so no consistency is evident yet. 

I think a better approximation of revenue is like somewhere in the $150 per day range, with $150 ad spend = $0 profit. This is evident from the graph. As there are 18 or so days of less than $150 in revenue (after the 50% calc has been done from the conversion rate).
