As a diabetic this reminds me of the conversation we had about the accuracy of diabetic blood glucose meters. By federal standards a diabetic blood glucose meter only needs to be 80% accurate. This alone can be it's own problem. But if you want lab results then go to the lab. If you want a general indication of daily trends, which is how we use blood glucose meters and tire gauges, then any gauge that is consistent in it's reading is all you need.
If I needed to inflate my tires to say 80 pounds, and the meter read 80 when I actually had 75, as long as it is consistent for all the tires. That is if it reads high or low, as long as it reads the same, consistently high or low for each tire.
