What do you think about the nub theory on Ultrasound?

So I am currently 13 weeks pregnant with my second my husband does have two kids before me to girls in this will be his fourth girl we really want a boy the heartbeat is 154 at eight weeks 
On an ultrasound my  placenta is on the left side, we went to my 11 week ultrasound to do the NT test and ultrasound. Technician said she could do the nub theory to get the gender and we let her she did a 3-D as well  my husband is is already saying it’s a girl because that’s what the ultrasound technician said I’m wondering how accurate is it  auction technician said it’s a girl and my husband really believes her but I read online that it’s only like 65 to 80% accurate before 12 weeks I’m just wondering what my chances are what do you guys think of the nub theory
was it accurate for you 
What week did you have it done?
Do you believe in it
I know there is no nub and the ultrasound I just thought I’d share a few pictures
