^Thanks for the info but I'm not sure what you are trying to say. I have compact rings in 3 bikes and never have any real issues with shifting nor do I notice much difference between the compact and the cross setup. My thought was going with 48/34 rings on the "compact" crank would give a bit better mix of ranges on the cross bike - a lower low and a higher high and still slightly better shifting than 50/34 (though I don't really see that as an issue/benefit).
