Eric -
I don't think you're going to find an exactly on-point case that instructs courts to divide "quality time" (weekends, assuming parent works M-F) versus "quantity of time". It's more common sense than case law as to scheduling time with parents, although O'Connor v. O'Connor, 349 N.J. Super. 381 (App.Div. 2002) (online at http://scholar.google.com/scholar_case?case=5575157028745297261 ) and Cipriani v. Fontana (Unpublished, April 2014, online at http://scholar.google.com/scholar_case?case=7027688687636945490 ) both make reference to "quality time" as a consideration when awarding and discussing shared parenting.
I'd also reference the whole Beck v. Beck line of cases (see http://scholar.google.com/scholar?hl=en&as_sdt=4,31&q=beck+shared+parenting&scisbd=2 ) and the evolution over the past 20 years away from parent-child relationships consisting of one "visitor" and one "parent" and toward a system-wide recognition that kids' best interests are served by sharing the burdens and joys of shared parenting when both parents are capable and interested. It's implicit in that idea that neither parent should be just the "fun" / weekend parent, leaving the other parent the less interesting (but still rewarding) day-to-day parenting responsibilities (or, as said to several folks seeking shared parenting who otherwise would have been visitors ... "be careful what you ask for... you might get it.")
