Er, there is a difference between accuracy, and precision.

An accuracy of 10 decimal digits of latitude/longitude would
correspond to about 10 micro-metres on the Earth's surface. Which is
impossible, unless the Election Commission has moved on from its
*unhackable* EVMs to unparalleled accuracy in measurement.

In other words, their ten decimal digits of precision mean only that
whoever made those entries probably had little idea of what they
were doing.
