Now I am new to this part of the website, but i don't know when the rating update is.
I have played in 3 sanctioned tournys, and only one has showed up(Bowling Green Ams) and i didn't even get a rating.
I am very confused, can someone enlighten me?

Please read the Ratings FAQ and the Ratings documents. They are all online here:
http://www.pdga.com/faq
http://www.pdga.com/ratings

The next ratings update date is at the top of the PDGA Announcements section on the Home page (May 19).

Thank you, i haven't explored that part of the website yet.:D
