This is true, I mean it is difficult because we are bombared with too much official documentation that depicts how certain actions should be carried out, RT is no different.
I agree that what is stated and what actually happens is different, though I have to say, what does amuse me, is:
"G-MS, contact approach on 119 day cee mal 5" lol
I've only ever heard one controller say that. Even my RT examer informed us that this was in place for old radio purposes whereby transmition was alot poorer quality.
