I think the problem is that the devs are experts in Java and programing languages, but not in Excel. Excel has a learning curve much higher than WORD.
Actually we have quite a detailed model in Excel since 21th thanks to Bitseed, however we decided to use it for internal reference only, as it does not include Maxmint data (which could be sent from same BTC address multiple times), not provides interactive marking of accounts to be refunded, nor provides any search facility via Bter ID while still preserving the ID's privacy.
Unfortunately, programming the formula and running with it over the whole data-set, has proven to be somewhat more time consuming than expected.
For sure!! I could see how much time this would take.. publicly viewable.. privately searchable.. floating percentages... It's not just a spreadsheet..
I forsee a potential problem in the future:
... A first day (30% bonus) investor/investors with a 10BTC investment refunds/sells their CRSHARE to Bter. Several 4th day (26% investors) investors on the waiting list are advanced to the payout list. There is a 4520 CXX difference per BTC invested between the 30% and 26% investors
This then results in a shift in the amount of CXX for every investor, as now 45200 CXX will need to be reallocated among the original investors. It averages 60 CXX per BTC invested. Chump change, but significant to a 15BTC investor.
My suggestion is that if this occurs, and investors ask for refunds after the ledger is published, that the CXX difference between the refunded shares and the waiting list shares be used for CXX development/promotion.
