What is calculus good for?
It is used to create mathematical models in order to arrive into an optimal solution. For example, in physics, calculus is used in a lot of its concepts. Among the physical concepts that use concepts of calculus include motion, electricity, heat, light, ""HARMONICS"", acoustics, astronomy, and dynamics.
I wouldn't take any gartley pattern as 100% accurate just use as a guide also if you know how to use the calculus you can create your own methods maybe better.!
Has somebody told you these patterns are 100% ???
Measuring them properly is a finely tuned skill takes time practice but i still wouldn't just trade purely of gartley pattern.
