A few more thoughts: shaky beginning, slight start, stuttering/hesitant/jerky start, slow start, five point start/handicap, extended opening, long introduction, unimpressive start, ...in the beginning (long ago, and probably in a galaxy far, far away...)
(This is the moment when Cheryl comes in with the right answer and makes it seem obvious!)
Unfortunately, Cheryl is not relaxing. Daughter's baby shower and furnace went out with wind chills -30! Off the top of my head: start at the right point?
