I do understand the difference, apparently you don't. Your own statement below proves this.

Strain gauge measurements can be take anywhere along the barrel.

If the strain gauge is placed near the muzzle , the metal that it is attached to, will never see the peak pressure, or the average pressure, it will only see the pressure remaining when the bullet passes that point in the barrel. Therefore the reading would be pretty much useless. Whether you use the copper crusher method, or the strain gauge method, the sensor needs to be placed where it will see the maximum pressure produced in the barrel, to provide the information required to produce safe loads.
