Those are your words. You also said it is not intuitive and is really only appropriate for prospective students. Here is what a dynamic replacement looks like when the math does the work.
Two things set the floor on time-to-completion. The first is unit load: 74 units at 15 units per term takes at least 5 terms. The second is prerequisite chains: BIOSCI 201 before 202 before NURSNG 112, and so on. When the chain is the bottleneck, adding more units per term does not help. Your counselors know this intuitively. The tool below makes it visible.
Sixteen courses. Seventy-four units. The prerequisite chain runs from BIOSCI 201 through NURSNG 240. At full-time pace, the fastest possible completion is eight terms. That is not a recommendation. It is a lower bound the computer proved.
This is the part Program Mapper could not do. Drag the unit cap and watch the terms reflow. When the chain is the bottleneck, adding more units does not help. Your counselors can show this to a student and the student can see exactly why.
The question you hear most: how much longer if I can only take two classes? Here is the answer for the prereq phase alone.
