If you have an SRM, Ergomo or Polar PM, do your workout files ever have watts = blank? I am using blank as a separate and distinct value from zero. In CP, a blank would show up as "---" instead of zero. If so, would you mind dumping the file as a PT CSV file and opening the CSV file with Notepad. What is in the file for watts at that row? It should be either zero or blank (i.e., spaces).
