Some of you get too wound up about your scales I reckon. You’re working up your own individual loads so as long as they repeatedly weigh the same weight consistently that you’ve settled on that’s good enough for most people apart from those precision shooters who use setups that rule out all human and mechanical error, which most don’t. Settle on a load weight, make a reference weight, check scale, load ammo, go shoot stuff, sleep easy at night.
Just remember the following:
Accuracy refers to how close measurements are to the true or accepted value. It’s the degree to which the result of a measurement reflects the actual value of the quantity being measured. Accuracy reflects the absence of error, both systematic and observational, in your measurement system.
Precision, on the other hand, is about the repeatability or consistency of measurements. It answers the question, “how close are measurements to each other?” Precision can exist without true accuracy; you can have measurements that are very consistent but still far from the known or accepted value.
Resolution in metrology equipment dictates the smallest change in a physical quantity that a measurement system can detect. It plays a pivotal role in determining both precision and accuracy, as higher resolution allows for finer distinctions in measurements
This will wind a few of you up but not worried. My system works well enough for my needs, others may find different. Have at it.
