Thanks for the response !!
Now, with that chart your comments make more sense to me now.
By my eye, it looks like OI has been pretty much flat/constant along the 45 horizontal until we get into Nov./Dec. where it starts to go up. Along with the Large Commercials .....
I really do not know how to interpret the vertical axis on this chart though ???
Maybe one day you will let on where that chart comes from !!???
