Hey Haejin, I had asked this question in a previous post..

But thought I'd re-ask since it was possible you missed reading it.. other steemians who want to learn also seem to be having the same doubts..
Started reading the book that you recommended by the way :)

Wanted to ask you if you could please tell us all how you do the eyeballing or estimation of how long each wave goes and what values you take to multiply the previous waves magnitude (e.g. 1.618 always or are there other values which you might use often).. also do you take into consideration the time elapsed to do it too.. Because there can always be multiple ways to label the waves if we just use basic rules... Would be great if you could do a separate video explaining the same..
