Hi,
This is a very interesting question, one that defies an exact answer.
As the definition of a “novice” implies that the person is new to the task it has to take into account the ability to absorb information, manipulation and dexterity in using tools & equipment, understanding the process, foreseeing obstacles & potential damage caused by actions to name a few.
As I don’t know you or your abilities I can guesstimate the other side of 6 hrs.
It’s actually easier to answer the question “how long is a piece of string”
Now that I can definitely answer.
Hope this helps
