It’s so messy, validating this sample tubing can be difficult. So what are these forces, what are the losses, and what are the acceptable results? Particle Physics...

By standardizing set-up variation where possible, these mechanisms are further classified into their principal loss mechanisms.

But why do the counts not match? The answer encompasses model, manufacturing, engineering design, and calibration.
