The more important point and my experience and as related by others, the use of coax which has foam dielectric in a tight radius bend has been proven or shown to be problematic. As to if the manufactures bending radius dimension is being violated, I find to be of little concern.

If hams choose to "stick to the rules 100% in all aspects of their stations"............I'd say 75% of the stuff we use and methods employed would put most of the station stuff in the trash.
