Not sure what do you mean by: 'their goal of being 35% of the network'.
Peta's strategy is to reinvest 35% of its net income and according to Cryptx's forecasts (a bit dated) Peta hash rate should represent around 1-2% of total hash power.
I hope I am not remembering a hallucination. I swear I saw it somewhere that there stated goal was to be in control of 35% of the total network hashrate.
I am going to keep hunting and if I find it I will post a link to the source.
