We are investigating some issues with the Cw calculation for channels when designed as per the AISC 360-16 code. Due to a glitch, the software is using a higher value for Cw and that is causing the capacity to be overestimated and the utilization the ratio to go down. We are going to get this addressed in the upcoming release which is coming out in the next couple of months. For now specifically for channels, I would suggest going with the ratio that the AISC 360-10 is reporting.
