android users get very high GPS DOP readings
run.gps programmers, consider this:
/**
* Approximation factor for calculating Horizontal Dilution of Precision
* from location.getAccuracy(). location.getAccuracy() returns an accuracy measured
* in meters, and HDOP is obtained by dividing accuracy by this factor.
* The value is totally false (!), but is still useful for certain use case like
* track display in JOSM.
* See: http://code.google.com/p/osmtracker-android/issues/detail?id=15

public final static int HDOP_APPROXIMATION_FACTOR = 4;
