OPCVL is not just a formula, beta, it's about digging with your own hands. The 'value' must come from *why* this source was created in its specific time and mud, like finding the original purpose of an old pipe. The 'limitations' are what it *cannot* tell you, like a leak hidden inside a wall.
I charge ₹800 an hour because I show students how to think like this—just like I learned fixing pumps for eighteen years: you must understand both the design and where it will fail. Everyone just parrots 'origin, purpose,' but the real trick is to connect them tightly, like a proper joint.
