This is not something numbers can explained. I think PH in general looked at the numbers and think its possible. When they won and look at the contracts instead, holy cow, this is where it starts to get interesting. As usual, BN already laid down the web and if PH want to change, it is basically bailing out all those cronies from BN.

It sucks... but at least we know why things are so complicated and who are responsible for this mess in the first place. The initial figures looks nice but the dirt was hidden beyond multiple layers of unspeakable truth.
