Did anybody else have an issue with "She wants to see a 10% growth?", and then Excel autofills the following quarters linearly (+$100 / $200 / $300) not exponentially (+10%)?
Never extrapolate your cells from just 2 fields folks!

And to be honest, the inputs they have to deal with are uncertain enough that in the end, pretending small-percent geometric growth is linear is not going to be the dominating term of the error.
In this case... meh. Actual geometric model gives a sum of 5.11 for the year, whereas linear approximation is 5.00 -- an underestimation of just over 2 %.
Do you really think the 10 % assumption we went in with is accurate to ± 0.2 percentage points?
