Yep, Diadem, thanks for backing up my maths - there is one flaw. That assumes that we wont increase our crack rates (ie. no new computers joining and cracking continueing at the same rate), which is not going to happen. In fact as distributed computing speeds increase, more people join, the speed at which we approach the key increases - which adversely effects you reaching 1st place (and us also). Example, if tomorrow everybody cracks twice as much as normal on other teams (not us or DPC), you would have to effectively double the 350k blocks to 700k as we are approaching the key at twice the speed.
In a way I prefer talking like this, as opposed to "Move outta the way, the DPC train is coming". Aye, it is coming, but at least like this we have an estimated arrival time. 🙂
