Chinese Gender Chart

Anyone else think that the Chinese Gender Chart is bunch of bologna? Some people swear by it and say that it is SO accurate, but come on! If you aren't familiar with how it works, it takes your age and the month that you conceived and tells you whether you are having a boy or a girl. But that makes NO sense whatsoever! The prediction it gave me was that I was going to have a boy, because I was 25 years old at the age of conception and I conceived in the month of August. So that means that every 25 year old in the world who gets pregnant in the month of August is going to have a boy??! Crazy. But the thing is, this particular gender chart is EVERYWHERE! Of course, it has a 50/50 chance of being right, lol. By the way, it predicted that Max was going to be a girl, lol. I just think it's silly to use that type of logic to tell what the gender is.
Now the pendulum test...now there's a prediction worth doing, hehe...
