at the moment, it says that 1% profit edge is 15,678 BTC, when your graph show it to be above 50.000 BTC. not difficult to understand, which figure is correct.
one thing i come up with is maybe it's because bitcoinproject.net stats starts only from 12 Oct 2013, which is after nakowa, but then again - how this could previous data have not been taken into consideration?
As you mentioned, BitcoinProject doesn't include data from the start of JD, the graphs Dooglus has made do.
