1.   Schemata progress from being less accurate to being more accurate.

2.   It must be remembered that computers are usually accurate to only six or seven decimal figures.

3.   And error-correction techniques have advanced so that specialized GPS devices can be accurate to the width of a golf ball.

4.   At some sites open to any cook who wishes to post, recipes range from authentic and accurate to simply wrong all around.

5.   Atomic clocks calculate the passage of time by measuring the vibration of cesium atoms, which are accurate to within a few billionths of a second per day.

6.   Because the time is transmitted over a computer network, delays in the network mean the time is only accurate to plus or minus one second.

7.   A new type of atomic clock has the potential to do far better, to be accurate to within a second every few billion years.

8.   Both labels are accurate to a point but prove too limiting.

9.   But now, a new type of atomic clock has the potential to do far better, to be accurate to within a second every few billion years.

10.   Data are updated four times a second, and the system is accurate to within half a meter.
