Here in the South West it's about 200m where we are 'logged' on scene regardless as to whether 'TerribleFix' has it right or not. Also regardless as to whether the scene is 'safe' or not. We are constantly questioned as to why it took us more than 8 minutes. The latest cunning stunt is constant phone calls from control once we have reached hospital requiring a reason if we are more than 1 second over 20 minutes.... I have had the phone ringing in my pocket while assisting in resus with CPR. My stock reply is "assisting with patient, and yes the patient is fine (or the patient is now deceased), but thanks for asking!" A previous reply is absolutely correct. Lets have a system whereby we audit by patient outcome and not bl**dy times! A system whereby if I reach a patient who is in cardiac arrest in 9 minutes and resus that patient is considered a failure, but if I reach the patient within 8 minutes and can unfortunately do nothing but it is still considered a success is an absolute farce!
