How much money does Zynga make from sales of Tier 8 units?

I was curious how many Tier 8 units were offered for sale--in particular, how many Triton Carriers since that's what's currently on sale.  To figure this out, I pieced together two pieces of information that I gathered at nearly the same time.

Data

First, the image above tells us that 44% of the total Triton Carriers offered for sale have been claimed.  That means 56% have been sold.

Second, I used Charles Proxy to find out how many Triton Carriers are currently available for sale.  The image below tells us that that number is 341.

Estimate of how many are for sale

It's critical that I got these two pieces of information less than one minute apart because that means they can be combined.  If 341 units are left, 44% have been claimed, and 56% have been sold, then that means approximately 341 / 0.56 ~  609 were originally offered for sale.

I repeated this procedure a few more times.  From all my data and from the fact that a nice, round number is more likely, I think it's safe to say that 600 Triton Carriers were originally offered for sale.


How much money does that make Zynga?

Each Triton costs 800 Empire Points, so 600 of them cost a total of 600 * 800 = 480,000 EP.  Let's say 1 EP = 0.10 USD.  Then each Triton costs 80 USD, and 600 of them cost 48,000 USD.

Assuming an average discount on EP purchase of 20%, the exchange rate is 1 EP = 0.08 USD.  Then each Triton costs 64 USD, and 600 of them cost 38,400 USD.  This assumes all EP used to buy Triton Carriers are paid for in USD or an equivalent rate in other currencies.

Assuming Zynga actually sells all 600 units, they earn around 38,400 USD.  This may not actually be the case as we know the Pegasus was only 87% claimed at the end of its offering period.

I don't know how many of the other Tier 8 units were offered for sale or how many of the future ones will be.  Let's assume 600 of each.  From all nine Tier 8 unit types, Zynga will take in revenue of around 9 * 38,400 = 345,600 USD.

I assumed the 600 units per Tier 8 unit class were for the whole world.  It's possible that it's just for the U.S. or for a particular set of game servers that I happen to be associated with.
