Quality vs. quantity of fathering time: An argument against shared physical custody

What does my meta-analysis (and Amato and Keith's meta-analysis) tell us about the importance of father contact and how do both of those meta-analyses "translate" into a position that supports shared physical custody after parents separate? Should my meta-analysis (and Amato's) be used as evidence against shared physical custody by claiming that fathers can create and maintain high quality relationships throughout the many years of their children's childhood with slices and dices of parenting time on weekends and vacations? Do my findings support the idea that kids benefit from overnights and extended stays during the school week vs. weekends with their dads?
