Egg value doubling research question Is there a difference in earnings between buying upgrades in the same tier before getting one that doubles the egg value? A friend asked and it had me wondering. I assumed that the value doubling is applied separately from the other value increases. 

So it would be (X = X + (percentage increase of other upgrades) + (double value upgrade)) 

And not (X = X + (percentage increase of other upgrades) * (double value upgrade))

Thanks in advance.
