Yes. We currently do that, though in C, not Erlang. 

Whether it's useful or not is another question. But it sure is lame to
display 101%. It's also lame when you have two identical test systems
listening to the same link from a test generator and one consistently
says 56% and the other consistently 57%. Gets people asking "why can't
they agree, they're the same, aren't they?".
