Hi bf,

» I was using the 100/112/125 example...

there are two things in this:

1. In some cases the usual 80.00%-125.00% criterion may not be optimal and in those cases alternatives must be sought.
   
2. I am not aware of any problem of any kind, which has practical relevance and which can be solved by imposing a mandatory span for the CI across the 100% mark.

The example you mention appears very hypothetical, doesn't it?
If it existed that way then you could definbitely do a Finney bioassay to derive relative potency and a CI of the same. Now that's a horse of another color.
