I don't understand the question, but should point out that precision and accuracy are not the same thing.
Accuracy is how close your outcome is to the target. Precision the repeatability of the outcome, regardless of how close to the target.
If for example, your goal was 10, your results had an average of 10 + or - 30%, you could say that your results are accurate, but not very precise. If your results were instead 10,000 + or - 1%, then your results would be much less accurate, while being much more precise. Saving Changes...

I agree with Keith - Maybe you can elaborate more on your question because accuracy and precision are different things. Saving Changes...

Seems to me that the more accurate the measurement the less precise one can be. One should be able to repeat low accuracy (+/- 30%) more readily than high accuracy (+/- 10%).
We are used to accuracy being expressed as +/- or as percentage of true value The same concept can be applied to precision. Thus one can qualify a measurement at 90% accurate with 50% precision. However, we may also measure at 50% accurate with 90% precision.
One is not better or worse than the other - it depends on what you are trying to achieve with the measurement. You can most likely portray them as curves and use the intersection point as "the ideal compromise". Saving Changes...
If you are working with an Automation System, precision is better than accuracy, because precision maintains a constant value of bias, that can be corrected with programation and compensate the difference from the desired value. Saving Changes...
