Simple huh? And you've used this to accurately predict the outcomes of your sales forecasts without fail?

It is simple to mechanically apply formulas to data sets, but it's far harder to account for unexpected biases and new events that happen that introduce non-representative data into the population.

So go ahead and do it, but I wouldn't rely on it very much - the process you're applying it to is subject to many discontinuities that you can't predict.
