Does halving a rack of ribs affect cook time?

[erikz]

So I have a 18.5" WSM.  I seem to be able to easily fit 2 racks of baby backs next to each other on the racks.  I've seen plenty of pictures of people that have to cut their racks in half to have them fit in their smokers. 

Does this change the cook times at all?  I could see myself being able to fit at least 2 more racks in there if I were to cut a couple in half and play a little rib tetris.  I don't wrap my ribs at all, I just let them go until they're done.

Nope...If you loaded up Rib Racks they take a little longer because of the added mass of cold meat but no change in this case...JJ
