Thanks for that babble.
I am not nor have I ever been in sales.I do not need the charts ,graphs , or babblespeak to support the facts.I have always worked with the end user of the Hyster product.My hands on the machines.My body in the building the truck was actually being used in.
Don't get me wrong I know full well how to use the charts and graphs of the coorperate world.I could ,for example, present a very convincing arguement that you are taller or shorter than you actually are using charts and graphs.
I still hear Billions and Billions of our burgers sold.Buy our same old burgers.Everyone else does.
More on your babble........
Your "quantitive data" comment moves into the world of the " Scientific Method" by which things are (supposedly)proved to be a scientific fact.The scientific method is a flawed device that only proves the existance of scientific theory with no absolute truth.Only truely useful in pointing out general direction such as saying " oh , that away".Scientific proven fact is overturned on a minute to minute basis.
My babble.
