@bill93 I suspect that most of us do the same thing. However, @geeoddmike raised an interesting question. For his example points, Inverse returns 311...

@geeoddmike Surely NGS doesn't just invent the numbers in the digits beyond, say, the third decimal place. On the other hand, maintaining sub-millime...
