Duplicate pairings

description

The current version of Matrix allows duplicate pairings that vary only slightly in time and distance. In this example, two entries are noted for the same long trail segment:
 
01:17:57 4.93 mph 3/27/2010 8:18:40 AM 6.40 mi Black Mountain + Vista Point elevation: 2,335 ft 0:00 ***
01:22:06 4.76 mph 3/27/2010 8:18:40 AM 6.51 mi Black Mountain + Vista Point elevation: 2,337 ft 0:00 ***
 
The Trails plugin data is reflected in the first entry.

Since 0.6 version, Matrix supports passing a point more than once, to support circuits, out-and-back etc. The algorithm when a a point is met has been tuned to not look for a best match if not the point is 4 times the radius (the first build reported here had 1.5 times the radius). In the case above, the point closest to the center would be selected (could be either of the end points).

This version of Matrix allows adding a point more than once, to for instance support out and back.
The issue is likely the algorithm to determine that you have left one point and started to look for next.

A test build with increased radius here:
