Another boy or a girl question, the Chinese gender prediction?

I know that all women of old tales and what not, but im hard to make my scanner and sexing the plot is driving me nuts lol. Just wondering if anyone of you have tried Chinese gender prediction and whether it was correct for you, assuming you know the sex. If you havent tried one and know the sex of your baby you can test it for me and let me know if it is correct or not. http://www.thelaboroflove.com/chart/pred.html <<<Link predictor: D I do know this is done, Im just having fun with it! I've told people this calculator to find entirely true;)

With my first he was right. My the second was wrong, but looking back when I was supposed to be designed just for my birthday. So if I'm going to age 24, it is bad, and if I go by 25, he is right. With him he was right. I use Google for testing gender of the baby, and fill them to see what I was doing. They have been so much fun!
