I have a What-If Parameter that let's you input a certain investment amount ($). Based on the amount entered, it calculates your total savings. Here is an example. Recommended Incremental (Per Hour) is the investment amount ($) and incremental savings is the savings.
We run this multiple times for different scenarios to understand what the investment amount is that yields the highest savings. Is there a way we can automatically get the investment amounts for each instance where savings is maximized?
