I disagree. I don't think it works for the majority well at all and its especially poor for older people because their max heart rate calculated by this method is far too low. This means that older people using this method would tend to not exercise at a high enough heart rate, which is not a good thing at all. There are plenty of publications that back up the idea that 22 - age is nonsense.
