Missing the first test seems to be quite common.
Being pushed to the limit in the previous season only really hinders a team if there is a big rule change, like McLaren and Ferrari suffered in 2009. With there being very little difference in the rules between 2012 and 2013 I don't think theres much to worry about RBR being a little late.
