Hello Russell
Well it is a risk assessment tool and not a simulation...
To answer one part of your post...
If the variance of a parameter has very little to no impact on the overall model output, then frankly 'don't sweat the small stuff'. Choose a conservative value and move on. It's not lazy, it's nicely pragmatic.
There are more important things to worry about, rather than getting concerned over a value that doesn't really matter to overall model output (which is essentially what the C4SL team did via their parameter analysis?).
