Isn't it something that this toy has become a necessity for jobs done quite well for decades without it?
As I pointed out, pressure/velocity is NOT same for different guns, so a chrono can not be used as a reliable pressure indicator, unless you have "calibrated" with the gun in question.
The main answer is the same: a chrono is FAR from a necessity and is simply a toy for most. Fun to know, but not required--except specifically for power factor and external ballistics at long range.
