Network total   1375352.598 Thash/s
Blocks/hour   5.40 / 667 s   <<<<<<<<<<<<<<<< 5.40 should be 6.00 this is down 10%

all of the above are most likely reflecting the turning off of .5 watt efficient  or worse gear

  and of course summer heat as most hashrate is north of the Equator.

 I am hoping for this to continue for this jump and all of August.

I would love to hit Sept at  a diff of 185 to 190.

After that it will be  upwards.

779 blocks in 5 days 20 hours 10 min

841 would be 0%

779/841-1 = -7.3721%  real time.

while -7.3721%  seems good  it is early.

but if we do that we will get under a diff of 200
