Seems they want formulaic answers...
How many wins/pts/podiums/trophies am i guaranteed per $ spent?
So... if we spend a lot of money, and we work hard, and get good drivers. Will we win?
What if... our competition beats us? how much do we need to beat them back?
Sorry folks, there's no guarantees in F1.
Or maybe they are still unsure because of the changing regs? who knows in a yr or 2 regs (specially engines) will be a bit more clear and it will be easier to make long term plans/investments and speculations... in the meantime, the russians and indians are diving in, by the time Porsche decides they might be racing behind the Ladas or Tatas

Came out fighting indeed.
