GENDER MYTHS AND WIVES' TALES ACCURACY (seeking feedback!) πŸ’™πŸ’—

I'm VERY curious to know how accurate gender myths and old wives' tales are for predicting what baby will be. There's something to be said for wise older women and their theories, but are they as good as science at predicting!?
We are waiting til birth to find out our baby's sex, but it seems like my gender myths are divided right down the middle. 
The "wives tales" seem to point exclusively to boy, while the more "scientific" predictions point exclusively to girl!  Which ones were MORE correct for you, or did you find that they were all a bunch of hocus pocus?  My results for the myths are below.
