Thank you Wim. Yes, this does partially illustrate (if not explain) why the lighting is different, but in no way helps me in determining a conversion formula, leaving me simply to eyeball it. Worse still, his approach of test rendering EVERY SINGLE SCENE with multiple settings is ridiculously impractical, AND Poser does not allow you to separate out the channels to see the impact in detail like Blender does. But thank you anyway.

It does not give a formula - correct. It does show however which bounce settings are important. It also shows you that a formula is rather difficult to determine since the branch path and non branched path renderers acting differently depending on the nodes used (blend for glossy/diffuse for instance). But the main reason I showed the video link is to explain the difference in light bounces.

I do support you with wanting to have additional render layers for spec, light, shadow, indirect light, etc. Those are very helpful.

Indeed. Thanks again Wim!
