Section 2.1, second paragraph - "may present as anomalies in measurements", perhaps change to "may introduce anomalies"?

How would you feel about "may appear as anomalies"? To me "introduce" sounds just a little too much like blaming anycast for causing a problem. Or maybe since this is the same section as the above item, it will likely all get rewritten in v3 so we save it until then?

Either is fine, or "may be present as anomalies", or "may present anomalies". The phrase "present as anomalies" just doesn't parse for me. Howard
