That would be a false degree of precision, not accuracy. Accuracy
refers to how close to correct something is. Precision is about
how fine you can measure something. While often related, the two
are not the same thing. It is entirely possible to have a ruler
with markings down to a micrometer, but that's off by 10 percent.
Here you've got precision, but poor accuracy.
