Go figure!

When Darien (my manager) and I were discussing a business case the other day, and we were deciding whether to include 5% or 10% as the expected growth figure, I suggested we split the difference and go 7.5%. No, he said, best to go for a round figure: using an exact figure like 7.5 suggests you have specific information to support that - 10% is a round figure and doesn't need to be supported as keenly (grasshopper!)
