I last did this when Michishige Sayumi graduated. Less than 4 months has passed since then, but there's still been quite a lot of shift due to changes at the top and bottom.

Originally Berryz Koubou: January 14, 2004 ℃-ute: June 11, 2005 S/mileage 1st generation: April 4, 2009 Morning Musume 9th generation: January 2, 2011 S/mileage 2nd generation: August 14, 2011

Morning Musume 10th generation: September 29, 2011 Morning Musume 11th generation: September 14, 2012

Juice=Juice: February 3, 2013

Morning Musume 12th generation: September 30, 2014

ANGERME 3rd generation: October 4, 2014 Country Girls: November 5, 2014 Kobushi Factory: January 2, 2015

Back in November the halfway mark of seniority was right between S/mileage 2nd gen and Morning Musume 10th gen. Of the current above list the halfway mark is in Juice=Juice, right between Kanazawa Tomoko and Takagi Sayuki. Nearly the entire lower half, though, are new people from within the last 6 months.
