I received .4 more BTC.  That gives me a price of $476.257605/(.4 + 3.70151298) = $116.117541825 per bitcoin.

I made this purchase on the april 12 2013.  04/12/2013.  at 1:35 PM Eastern Standard Time.  The MtGox chart uses UTC, which is 4 hours ahead, so it correlates with 18:35 MtGox time.  The purchase was processed by ZipZap at 2:21 EST, which is 19.21 UTC.  

Over this time, it was never near $116 per bitcoin.

The high for the 18:00 UTC hour was 89.7.  The high for the 19:00 hour was 95.89.

So, I am clearly still owed money.  You said earlier that the price was based on when the order was placed which would make the MAX price for me at $89.7 per BTC.  

$476.257605 / 89.7= 5.30944933 BTC
I have been paid 4.10151298 BTC.
So I am still owed, AT LEAST, 5.30944933 - 4.10151298 = 1.20793635 BTC

I really have no idea how the research team came up with the price it did.
