So, if we allow 10% G R&R the minimum tolerance that that system could measure would be 8 cc's!! Now that may seem ridiculous but that’s the results of the calculations. So how much error do you want to allow in the system? If the tech. stated that your combustion chamber was .5 cc small then that measurement was within the error of the two gages.
Also keep in mind some features are more difficult to measure than others. The most difficult are visual attributes or specifications. One persons course finish is another’s fine. A color (one of the most difficult) may look light blue to one person and medium blue to another.
The budget for the measuring system plays a big role. Like anything else, you get what you pay for.
