The statement is good.
In the past year or two I've provided race directors an information sheet which compares "typical-GPS-user-protocol" to the USATF/RRTC course measurement protocol.
There are days I want to provide counsel along the lines of Keith's "How to Protect Your Consumer-Grade GPS Unit From Needless Sun Exposure," but in many cases we might be the only exposure to the national governing body many runners have. A professional, courteous response can only help our work.
