KNC Sept/Oct 500TH/s is way too low, because September are day1+2 [1,7] only(?) and ~800 orders [2].
Most of the orders contain at least one Jupiter, few orders contain one Saturn [6] which has not upgraded meanwhile [speculation].
October orders are shipped on 11 business days, so lets assume another 11*(800/2)= 4400 orders (containing Mercuries as well).
According to knc-staff Jupiter will have at least 500GH/s [3].

So let's calculate with 0,5TH/s as an average per order [6]: (800 + 4400) * 0,5TH/s = 2.600TH/s
Maybe even more since there are orders with 6,8,10+ Jupiters [6].
Cloudhashing wanted to buy from knc as well [4], don't know whether they actually pre-ordered. If so I guess it's one huge order. Looks like they did [7].


Those days knc is shipping ppl will think the network-graph must be broken as it is showing hashrate increase at an angle of 88° or so until October 15th when last ones are shipped [5]. At least it will not be comparable to anything we saw before during this time x_X

“Currently we’re looking at 450 Th/sec that we expect to enter the network between September and the end of October,” Cole predicts. That will mean substantially increased difficulty as more miners come onstream.
