we are still not keeping up with predicted difficulty increase (18.48% https://bitcoinwisdom.com/bitcoin/difficulty)... We only increased hash by 13-16%. if we keep getting equipment weekly at 20TH per week we may be able to squeeze out some more div's per difficulty but thats if there isn't a supply problem which there clearly is.. 
You have wrong data.Last Monday PETA was around 108 Th/s, now 138 Th/s, that's 27.78 % increase, in a week!
On the last diff change I think PETA was hashing even lower than 108 Th/s. Anyone has that past data?

We can't base growth of dividends and hashpower on those #s, we are not fully deployed yet.
Once we are hashing @ 700+ths then we can determine our growth versus the network.
