How would you account for a physical job in your weekly TSS?

Reading through this thread I was about to ask if anyone had done just this in an attempt to approximate their activity at work. Obviously recording a 12hr RN shift wouldn’t be the same as your typical walk, nor would it equate to a run. But perhaps there is a modifier of sorts, akin to the IF for TSS, that could account for the mental toll?

I’m also in healthcare and frequently running around but, at this point, typically on 8-10hr shifts, and my other main athletic pursuit is rock climbing. How to quantify that atypical activity in terms of stress, especially if the loading is irregular or inconsistent?
