@TdeV
excellent questions .
Id advise you to get a
Red Engineering Lined book from
Stapes etc.
and not loose it
[ed.: Idiot rotuts , possibly ReCycled his. Idiot ]
you will learn in very short time
how to get everything Right for You
each time.
if you have under calculated
note that in The Red Book
Green covered books are a sort of Disease , so don't go there
Just PCook for a tiny bit more
remember , your re almost to your preferred point
and you are starting w Hot Water.
over time
a few weeks
you will be in The Zone
w the Red book.
