I think you're looking in the wrong bit of the API. I've heard back, and what I'm seeing isn't what you have in the above. However, I also can't post information that's not in the publically available documentation. Rocky documentation isn't in the normal install, so I need to see if it's in the imminent 22R2 version. 

What you do need to look for are some non-dimensional terms in the macros: I don't think you're adding the correct amount of heat.
