How far? I would have said... it depends entirely on the pilot, and on the training being conducted.
I have done not-very-competent touch & goes almost to a stop where LDR+TODR was about right. But then I have also done bounce & goes for no purpose at all except fun, which uses hardly any runway.
If you're an instructor, I think LDR+TODR keeps the accidents away, except full stop only at night as others have said. I wouldn't use the word never though - there's always a 4000m x 60m runway somewhere with bright lights and no terrain concerns!
