If someone's on a training approach I always try to ask how long a final they want. I find that a lot of folk want to start from 10 or 15 miles & 3000' to get max benefit from each approach (& fee). At the other end I try to minimise any climbing away from the airfield to save their pennies on miles they don't need.
With regard to rate "whatever" turns, I have two points.
1. My radar goes from "somewhere else" to ac, back from ac to "somewhere else", through a modem, down a telephone line, through another modem and arrives at my screen about a week later, so anything I see has already happened.
2. In my 12 yrs of radar no two pilots' interpretations of a rate-one turn have ever been the same.
Because of the above I gauge the rate of turn early on where it's less crucial and take a slightly more cautious pattern.
I would really try not to upset a pilot over the r't cos it just makes my job even harder!
