As has been pointed out before, there are uses of "CW" in EP notes that make it clear that CW is not a person. As mike tesko acknowledges that August billing details for the farm have not been released by EP, any times of calls they give are not known. References to 3:15/3:16 in police logs compiled later are useless, as these logs are suspected to be partly fictional. Also, it's essentially ridiculous to claim the police HQ information room clocks at Chelmsford were ten minutes fast and that coincidentally Pc West, using a different clock, made a separate further ten minute error (or independent twenty minute error) in noting the time of Jeremy's call as 3:36.
