It's the best thing there is if you've got absolutely no other reference point. If you've got any other reference point (like an HRM reading) then you can throw away the 220-age estimation.
There are approximations that give a better fit (population wide) if you use a second order polynomial but that is beyond the branes of most people.

When I did did my coaching badges and A Level Sports Science (over 20 years ago now) we were taught that a good rule of thumb for maximum HR is 220 minus your age.
