Good job, OmikronWarrior! Thanks for doing that, I like looking at numbers.
It's true that Growth gives more benefits than just money, like you say. But, unfortunately, your chart there I think quantifies what most people have been saying for some time now --that Growth as a money-making strategy is just not as good as Order.
It seems that the break-even point is around turn 50 or so, according to your chart. At that point, Growth and Order will give you about equal extra money per turn. And, this is even assuming that the growth scale was in each of those provinces from the start of the game, which of course isn't true. So, in reality, we're looking at more of a turn 60-70 or so break-even point, maybe even later. On a really big map, Growth may work out to be better than Order, but for most games, the money you get from turn 1 to turn 70 will be a much bigger incentive, so Order would be better.
And this isn't even factoring in that at the "break-even point", Growth will still be far behind Order in terms of money gained to that point.
This seems like good evidence that either Growth should be changed to at least +3% (as in CB mod), or that Order should be lowered to maybe +6 or +5%. Alternatively, the Growth % per turn could be raised.
