Cuyahoga + Medina is 12.469 house districts. At some point, it may be questionable whether you may apportion 12 districts to an area that is entitled to essentially 12-1/2, just because the error is less than 5%. You would be following the rules, but have lost sight of the underlying principle.
I remember reading that NYC was given two more Assembly seats than it's population warrented in 2001 by taking advantage of the 5% rule, and that the Senate (even counting prisoners in the prisons where they lived as of the 2000 census which was then the standard (and still is according to some)) had like an extra half a Senate district upstate. Of course, that was before the sucessful challenge of the legislative redistricting plans in Georgia.
