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 (with BTC that could be sent from same addresses 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. That said, we are there now and now reviewing all before bringing the ledger back online.
