I did worry that might be the case. I was hoping they’d be clear enough given that they can be read alongside the Guesstimate model, but I wasn’t sure about that. And your suggestion of at least adding brackets definitely seems logical, so I’ve now done that. (I’ve also now put the equations on new, indented lines.)
Also since x*y*z + x*y*(1-z) = xy, the above equations can be rewritten as:
I considered that approach too. It’s obviously valid, and does de-clutter things. But I sort-of feel like it’s still best to stick to just a plain presentation of the equations one would initially get from the MEC-E formula, rather than also adding the step of rearranging/rewriting.
