Track length accuracy

[TeDDy]

I can point you to my algorithm, but you have to compare it:

First look, I see you use the maximum radius too(somewhere in the sources founded 6371000m), and the file pointed differ from the same file founded on zip source, perhaps my mistake.
Can you test against the haversine form my EXCEL?

I will digg to see what results I get and I came back.

Thank you again.
