Hey Guys, little help here. Still trying to get used to the new SBR format. Couple questions.

1. Sportsbooks constantly change positions on SBR when viewing the lines. Also noticed there are no "grades" anymore i.e. A, B, C books. Is it safe to assume the first page are the A books, second page B, and so on?

2. When SBR states openers, is it still using 5 dimes as the overall sportsbook opener, along with line movement?
