It is Robert.

Have you hear about "Refactoring" -- new modern ideas
    general for any programming language.

A lots of useful things.
I can give you ref on book.

Now I say to our developers:
    Cut the hand which produce doubling code!!!

You talk here about

A) seed optimization based on LOOP INVARIANT.

B) Refactoring teach:

    a) yes, move out from loop.
        but you point here only first step.
        as you ay you will get doubling code

    b) refactoring require now second step:
        EXTRACT METHOD STEP: move that doubling code into separate
            function. So you will have just SINGLE code.
