OK, updated version attached.  I added "potential" to the first
paragraph, and added "estimated cost" to the later part, fixed the
"cheaper than", and clarified that we add the plan time cost to the
non-generic plan, which is how it can be cheaper than the generic plan.
I also moved the "Once a generic plan is chosen" line.

Yeah, that's a lot of changes, but they all improved the text.  Thanks.
