Pack Horse, the 2.5 minutes was clearly written by those who should, after writing it, been packed off to a care home for people living with dementia. It has no basis, as was admitted by those responsible for the guide after it was published but was just an arbitrary figure because they had no idea how long, in practice, it took to evacuate a sub-compartment. CFOA stated publicly at a conference soon after the guidance was published that they were "disappointed" with that recommendation. Accordingly, NASHICS subsequently, in conjunction with CFOA as was (now known as the Norwegian Forest Cats Club) produced guidance, which has subsequently been revised and still says the same thing, namely that it is often impossible to meet the 2.5 minutes time. Unfortunately, when it suits them, some FRS trot out the 2.5 minutes.
