Indeed not, I don't disagree.
Quick and good aren't always mutually exclusive though, sometimes an "intensive" course is the best solution for the individual concerned.
There's not usually a rush, we do more NRs in the traditional, hour or two a night manner. However, the customer might find it easier to be available for a single whole night, rather than several part nights. A couple of times we've had someone heading for a CPL need it done in a hurry in Summer.
You presume correctly.
