How do you do the run/walk off the stage>shine>turnaround>up+b>sweetspot the ledge?

So yeah it is just the question above, more specifficaly, how do you do the turaround part? do you do a semi circle with the stick from down to up? after yo shine do you tap up at an angle to do both turnaroun and jump? or any other method?

I'm having a hard time mastering this technic that seems to be easy to most people. Any suggestion will be really appreciated.

I run, press down b, reset stick to neutral, then up b towards the ledge. It has pretty lenient timing, you just gotta get a feel for it.
