The first point to check is the amount of mastercoins bought before 1.9.2013.
My calculation is available on:
http://pastebin.com/HiPVUxzTwhere you can see on each line:
- the block on which the tx was confirmed
- txid
- amount of satoshis
- amount of mastercoins (+ the calculated 10% bonus per week)
- the amount of seconds the tx was sent before 1.9.2013
Summing up the amounts gives a total of roughly
528,301 Mastercoins (or 528301.88871472 to be exact).
superfluouso calculated a total of around 554,297, so we do have a discrepancy here.
Indeed my calculation sums up to 528301.88871472
I assume the reasons for the difference may be:
- The 14 tx which are "mastercoin purchase" if one looks at blockchain.info "Received time", but they got confirmed only after the deadline, so the protocol does not consider them as purchases (see "Things to note" on https://bitcointalk.org/index.php?topic=265488.msg3088012#msg3088012)
- The timestamp for tx is taken as the timestamp of the first block in which this tx got included (again, see "Thing to note")
- Including the early mastercoin sending tx (which are per definition also mastercoin purchases if they are sent before 1.9.2013)
- Accuracy in calculation with rounding to full mastercoin smallest unit (100,000,000 dacoinminsters = 1 mastercoin?)
Since I gave all the calculation steps (including seconds till 1.9.2013 and bonus), it would be easy to check for a mistake.
Please update if you get the same amount for your address or not.
Anyone?
