When a pattern tells you to do a rib and you do it twice to get into it, then it says, continue doing the same until 45 rows have been knitted, does the 45 include the first 2 rows or is the total 47?
In this case I believe it means a total of 45 rows.
Depending on what you're knitting it may not make a difference though. If you include what you're making and a pattern link it's helpful when you're asking questions.
