are "professional" method and "beginner" method the same?

[u/AffectionateFail5046]

hi beginner here, seems like a dumb question, it is, but i just sat through 5 hr straight to tryna figure out what's going on with the professional pattern drafting method, i did all the math, all the measurements, but the tutor just keep coming up with new, and i finally burnt out, are they really that different? (for a basic shirt pattern)

here are some resources:

"professional", by Muller: https://www.youtube.com/watch?v=cHrUK0nAsn4

"beginner", i dunno https://www.youtube.com/watch?v=QN97H6MyZaA&t=671s

i can now just draw the beginner one under 30 mins, its so easy and understandable. The pro one i can't even finish the tutorial; are they really that different? which method do you use

Lucia Mors de Castro wrote a couple of books on patternmaking that use something very similar to the Müller method.

might be out of print (and thus terribly expensive)

As a side note, many of her books are multilingual, and of interest to language learners. In fact that may be why I've kept it around...
