The only ratio I find consistent enough to even look at is the 1.618 third wave (compared to the 1st) S wave or rather my personal opinion of market waves are that they are a complex combination of double zig zags. E wave recognizes and defines a zig zag, however considers them to be rare. I find wave pattern counting to be insufficient by itself and indicators, forks, channels etc. need to be included and may even be more useful.
