I'm a non native English speaker writing a dissertation in British English. In the dissertation I'm explaining a new advanced form of a certain method (let's call this method "x"). Because of word limit I wish to omit any explanation of the standard form of "x", since usage of this form is widespread in my field. Would it be considered rude to write something like the following?
We assume the reader is knowledgeable about standard 'x', so these will not be explained in this document. Instead we will focus on the new capabilities provided by "advanced x".
