...how can you prove that unless the exposure times exceed long periods as well? And, that needs to occur before it is proven. Sort of like begging the question, I think.
You're right, but only if you make the assumption that Marketing Time must be supported by hard data or "proven." So, in a way, you're actually begging the question regarding how predictions must be substantiated. If the only acceptable way to estimate Marketing Time was by extrapolating a trend line based on historical Exposure Times, you'd be right - this would be a huge conundrum.
But, you've just developed a trend line that indicates a consistent six month Exposure Time when the dog walks in with the morning paper (and a cup of coffee if he's a really good dog) with the headline reading, "Plant Closing to Cause Widespread Unemployment." The crystal ball comes out and the projected trend line (Marketing Time) takes a sharp turn up.
Exposure Time is a conclusion, based on data.
Marketing Time is a prediction, based on a combination of data, logic, and intuition.
