I have been searching for a reasonably definitive answer as to whether an AP400 mount can handle my 10" SCT OTA for visual use. The AP site lists the capacity of 18 lbs, but I also read that they use a load capacity for astrophotography, which I gather is about half of the load capacity for visual observation.

Any advice appreciated.

Hard to say, I stupidly sold mine many years ago. I found that for astro-photography the 400QMD was a bit light for a 130EDT plus camera and guidescope which probably dressed out to nearly 28 pounds. Mostly I recall the degradation was tracking accuracy and not a huge amount of bounce although that was after switching to the 6" pier as opposed to the hardwood tripod which did start to add shakes with that load.

I only had the 130EDT then but I think it'd be light for a 10" SCT but should be lots better than a CG5 so depends on your standards and how windy it is where you observe.

My friend has a C11 on his pre GO-TO AP400 and it does very well.

I had the same AP400 mount years back and it was more than enough for a C8.

I had the 400 QMD and it handled my C11 just fine for visual use.
