When calculated in the OP over the time period from March 14, 2013 to March 13, 2014 the average increase in the difficulty and hash rate was 23.92% per adjustment period and the average length of each adjustment period was 11.38 days.

Recalculated over the period June 29, 2013 to June 29, 2014 it was 23.45% and 11.41 days.

Now, recalculating over the period August 24, 2013 to August 31, 2014 it is 21.12% and 11.63 days.

Assuming the network growth rate over the next year is the same as it was this last year we get:

In other words something has got to give by the end of the year, or actually before December 1

A damn fucking shame that hashrate declined...
